If the switch on the dome light is switched off, dsims harness will still receive the negative trigger from the door switch and still turn on your rock lights, given that you also had tapped into a 12 volt constant also.

Working hard to try and get another batch done. I am hoping tonight I can finish for another drop tomorrow.

After this batch I will be taking a 2 week hiatus for a 4000 mile overlanding trip to Colorado. So if you want in, be sure to jump quickly at this next batch

RisingWithoutWings · May 7, 2018

I am in for the next batch. Thank you

Loudog504 · May 7, 2018

Great... now i need rock lights. You know for when i drop my keys at night.

*Edit* I don't even carry keys, i have the credit card key now... Guess i just want it lol.

Flanny · May 7, 2018

Also in for the next batch

Loudog504 · May 7, 2018

Same here.

DSIM · May 8, 2018

So I've been in the lab... Got six ready to go. Will not have another batch until late may due to an upcoming overlanding trip. First come first serve via PM as always.

Also, check out the test rig for these I made. Lot easier to test them on the table then going out to the rig uninstalling mine and installing each one of six to test. Also is a good way to show functionality. Anyways... Check it out.

RisingWithoutWings · May 8, 2018

Just sent you a PM.

DSIM · May 8, 2018

3/6 Claimed and paid.

3 left folks.

DSIM · May 8, 2018

5/6 claimed. Awaiting 5th payment. 1 left for grabs.

DSIM · May 9, 2018

SOLD OUT.

Will ship units for the third batch today.

As stated before I will be on a long overlanding trip (NC to CO) over the next two weeks starting Friday.

For any troubleshooting questions feel free to PM me but responses may be delayed.

Will plan the next batch upon my return.

Finished installing my @DSIM harness today. It took less than 15 minutes since I already have my switch and rock lights installed. All I needed was his harness and three quick splice connectors.

Big thanks to Daniel for a great product and being super helpful as I bombarded him with noobie questions. The harness works exactly as intended. My rock lights used to only come on with a physical switch but now they also come on with the dome light signal (approaching vehicle, unlocking vehicle, opening doors, etc). The harness is more than just a relay and has everything required to work as you need. The rock lights cut on/off instantly and don't dim which means the relays won't chatter and fail due to the included capacitor. The rock lights can also still be operated via the switch without powering on/impacting the dome light due to the included diode.

I also tied my footwell lights into this as well which only took a few minutes. Now, my footwell lights come on, in addition to the rock lights, with the dome light circuit (approaching vehicle, unlocking vehicle, opening doors, etc). I’m really happy with how it all came out.

For more pictures and info of my install, you can see my detailed install thread here.

Thanks!

Hello, friends!

I decided to compile all of my electrical write-ups in one thread.

This write-up includes:

LED front light bar

activated by physical switch

LED rock lights

activated by physical switch AND dome light signal (approaching vehicle, unlocking vehicle, opening doors, etc)

LED reverse lights

activated by physical switch AND stock reverse signal

LED footwell lights

activated by rock lights physical switch AND dome light signal (approaching vehicle, unlocking vehicle, opening doors, etc)

I also have @mesojdm LED map and dome lights with the door trigger disconnected for the dome light (allows for independent control of the dome light with the switch without dome light coming on with the doors).

Note: this is how I did it and I'm not the best electrically. It seemed like the most logical way but there could definitely be better approaches.

Huge thanks to @DSIM for coming up with a great product (referenced below in rock lights section) and for all of the help answering my relentless questions. Daniel is a great dude!

Instructions

Leave the main connections (battery positive and ground) connections for the end once you have all your wires routed as a precaution. Always start with negative battery terminal disconnected (use a 10mm socket) and cover terminal with a rag so it can't make contact.

Remove the grill. Use the phillips screwdriver to remove the two screws and the flat head screwdriver to remove the two plastic tab screws. Grab the upper supports and pull straight out. The plastic tabs will come out.

Remove the wind deflectors on each side. Use the flat head screwdriver to remove the single plastic tab screw on each side.

Remove the two transmission cooler bolts by using the 12mm deep socket. Push the transmission cooler back to make it easier to slide the LED light bar in.

Remove the two nuts on each of the outer sides of each crash bar with the 14mm deep socket. Leave the inner bolts alone. Install only the driver side light bar bracket but only hand-tighten the nuts.

Slide in the light bar from the passenger side to the driver side. Let it rest on the crash bars. Install the passenger side bracket and hand-tighten the nuts. Use the smaller bolts that came with the light bar to attach the light bar to the brackets with a 5mm allen key. I also added two hardened washers (one on each side) but they likely aren’t needed. You may need a second person to hold the light bar as you bolt the light bar to the bracket so that you can lean down to see through the grill to line up the bolts and holes. Ensure that the light bar is pulled all the way forward and rotated to face straight out.

Mount the relay to the bracket by the battery by temporarily removing the bolt with a 10mm socket.

Cut off the spade terminals from the white and black wires from the harness, cut it shorter to length, and use the 14 AWG butt connectors to connect it to the red and black light bar wires (white to red, black to black). Use electrical tape over the connectors. Use electrical tape over the second set of white and black wires from the harness or cut them off if you don't plan to use them (they are for a second light bar).

Temporarily run the two red terminals to the positive battery terminal and the two black terminals to the ground to the right of the relay to test the light bar. Use the attached switch. If it works, disconnect the terminals. If it doesn’t, troubleshoot. The battery terminal requires a12mm socket and the ground requires a 10mm socket.

Reinstall the transmission cooler

Cut off small corners of the wind deflectors with a dremel and then reinstall. This is so that it doesn’t hit the light bar.

Zip tie the wire going from the light bar to the relay in various places to keep it out of the way. There are plenty of places to attach too.

Follow @moe2o4 ’s guide to disassemble the dash panels. Use trim removal tool, 10mm socket, and phillips screwdriver to remove three trim pieces on driver side.

If you're only installing one switch: Remove the blank switch place-holder from the far right. It unclips from the back and pushes to the front.

If you're installing multiple switches: Remove the cubby with a screwdriver.. It unscrews from the back. Screw in the new switch holder.

Cut off the switch from the harness. Cut off a straight piece of a metal hangar. Use the hanger wire to poke a hole in the rubber firewall. Use electrical tape to tape the red, white, and black wires coming from the relay to the hanger. Rub a dab of dish soap over the taped area of the hangar and then pull it through from the interior by pulling on the end of the hangar.

Wire the switch to the harness wires by using the 20 AWG butt connectors. Red harness wire goes to the green switch wire, white harness wire goes to the red 1 (first after green) switch wire, black harness wire goes to the black switch wire. After that, use the 20 AWG quick splice to connect the red 2 (second after green, first from black) switch wire to the green cargo wire (first wire on the first switch from the left). After you connect everything, wrap all the connects in electrical tape.

Reconnect the two two red terminals to the positive battery terminal and the two black terminals to the ground to test the light bar. By default, nothing is lit up. The switch text LED should light up when the interior lights are on. The switch light bar LED should come on when pressed. Test the new switch to make sure it works, that the lighter comes on, and the switch light bar LED should also light up. If it works, proceed. If it doesn’t, troubleshoot.

Ziptie the extra slack going from the relay to the firewall, from the firewall to the battery positive terminal, and from the firewall to the ground terminal. Reinstall the dash panels. Reinstall the grill.

Rock Lights

Instructions

Engine bay wiring

Always start with negative battery terminal disconnected (use a 10mm socket) and cover terminal with a rag so it can't make contact.

Run two power wires and two ground wires (for relay and switch) to battery and ground in side of engine bay using 12mm and 10mm socket respectively. Trim to right lengths utilizing 18AWG wire and butt connectors (heat shrunk with lighter, wrapped in electrical tape) as needed. Use wire loom (electrical tape on ends) over wires

Cut off switch. Use a sharp object (coat hanger, shish kabob stick, etc) to poke a hole in the rubber boot, with the switch wire electrical taped to it, to run the switch wire into the cab. Use wire loom to cover wire

Switch placement and wiring

Follow @moe2o4 ’s guide to disassemble the dash panels. Use trim removal tool, 10mm socket, and phillips screwdriver to remove three trim pieces on driver side.

If you're only installing one switch: Remove the blank switch place-holder from the far right. It unclips from the back and pushes to the front.

If you're installing multiple switches: Remove the cubby with a screwdriver.. It unscrews from the back. Screw in the new switch holder.

Push in switches

Use butt connectors (and electrical tape) to connect switch wires to switch

Use quick splice connector (and electrical tape) to connect switch wire to another switch wire for illumination

If you want the rock lights triggered by the dome light signal in addition to the physical switch (approaching vehicle, unlocking vehicle, opening doors, etc

Follow this Toyota guide on removing the a-pillar cover

Ziptie @DSIM relay to one of the factory harnesses

Follow @Volksparts guide on wiring in the @DSIM black wire. Feed @DSIM black wire up behind dash towards a-pillar and use quick splice connector to connect @DSIM black wire to yellow a-pillar wire

Use quick splice connectors to connect @DSIM red wire to switch green wire and @DSIM yellow wire to switch red 1 wire

Reassemble

Lights placement

Middle four lights were placed under each door, rear two lights were under the bumper, all were ziptied to the frame

Front two lights were under the front bumper. I made a paper template of the light by tracing it and used that to drill three holes (two mounting bolts and wire) into the flimsy plastic in the front of the truck under the bumper in front of the wheel well. I then mounted the lights using the two supplied bolts. I accessed the inside of the wheel well to secure the 10mm nut from the wheel well using the 10mm socket to hold the nut and the 5mm alley key to tighted the bolt. You access the wheel well by removing one 10mm bolt with the 10mm socket and one push screw with a flathead screwdriver from inside the wheel well and them pull the plastic aside.

Lights wiring

There are two wires from the relay for each side, each with two leads

Run one wire across back of engine bay facing cab ziptieing to existing harness as you go

Cut off wiring harness leads. Connect additional wire to one of the harness wire leads with butt connectors (and electrical tape, wrapped in wire loom) and run straight down to under truck

Run wire to first light (in wire loom) at the passenger front door ziptieing to existing harness as you go

Three way splice with two butt connectors (one for red positive wire and one for black negative wire). One side has the incoming wire. Other side has rock light wire twisted together with additional wire. I'd strip the wire for both the rock light and outgoing wire and then twist the strands together (do that for both red and black wires respectively). Wrap in electrical tape and then put in wire loom

Repeat above for passenger rear door, passenger rear bumper, driver rear bumper, driver rear door, driver front door (daisy chaining as you go with three way splice at each light, covering wire in wire loom as you go, ziptieing to existing harness as you go)

For the passenger front bumper, connect additional wire (with butt connectors) to the other lead from where you ran across the engine and where you ran the one lead down to under the truck, wrap in wire loom, and fish the wire down to the small opening in the bumper from behind the headlights. Connect the light to the wire and then push all of the extra wire back into the bumper

For the driver front bumper, you can now use the other primary wire coming from the relay. We'll only need the long lead so you can either cut off the extra one in the middle or just cover it electrical tape. Repeat process above for fishing the wire and connecting the light

Rear Lights

Instructions

Same as rock lights with the exception of drilling into the plastic part of the rear bumper with a 1.75" hole saw for the main hole for the light and 3/16" drill bit for the mount screw holes

If you want the new reverse lights to come on with stock reverse signal in addition to physical switch

Follow this EAA guide on how to solder a diode to 2-3 ft of wire and then put wire assembly inside wire loom

Use quick splice connector to connect one end of new wire to middle white wire of trailer harness and other end of new wire to red positive wire of wire leading to the reverse lights

Photos

Footwell Lights

Instructions

Always start with negative battery terminal disconnected (use a 10mm socket) and cover terminal with a rag so it can't make contact.

Follow @moe2o4 ’s guide to disassemble the dash panels. Use trim removal tool, 10mm socket, and phillips screwdriver to remove three trim pieces on driver side.

If your LEDs have a control box, mount it in desired location. I mounted mine using the supplied double-sided tape in the driver footwell area in the bottom right corner.

Use a quick splice connector to connect the red positive wire from the LED control box to the yellow @DSIM wire. I also added extra electrical tape around the plastic connectors with the fuse to ensure it doesn't come disconnected.

Use a quick splice connector to connect the black negative wire from the LED control box to the black wire from the rock light CH4x4 switch.

Pass two of the light bars through the small hole of the carpet under the console to the passenger side.

Run two of the light bars (one for each side) to under the seats while tucking the extra wire up and under the side of the wire console.

Secure light bars in desired locations using zipties and/or double-sided tape. I mounted mine at:

Driver side front: under dash with double-sided tape

Passenger side front: under dash with zipties using holes already in dash

Driver side rear: under front of driver seat using zipties around metal support bar

Passenger side rear: under front of passenger seat using zipties around metal support bar

Relay Holder

Instructions

This is only if your relays don't have the empty tab slot on the back to install onto the relay holder

Drill three holes into relay holder tabs to mount relays with zipties. If you buy relays from an auto parts store, they'll have a slot where the relay holder tabs will slide in. Since I used premade harnesses, they didn't have this

Spray paint over the new holes to avoid rust

I update my post above. I now have my rock lights and my footwell lights running off of @DSIM ’s harness. Both my rock lights and footwell lights come on with the dome light circuit (approaching vehicle, unlocking vehicle, opening doors, etc). They can still be independently operated via a switch.

Instructions

Leave the main connections (battery positive and ground) connections for the end once you have all your wires routed as a precaution. Always start with negative battery terminal disconnected (use a 10mm socket) and cover terminal with a rag so it can't make contact.

Remove the grill. Use the phillips screwdriver to remove the two screws and the flat head screwdriver to remove the two plastic tab screws. Grab the upper supports and pull straight out. The plastic tabs will come out.

Remove the wind deflectors on each side. Use the flat head screwdriver to remove the single plastic tab screw on each side.

Remove the two transmission cooler bolts by using the 12mm deep socket. Push the transmission cooler back to make it easier to slide the LED light bar in.

Remove the two nuts on each of the outer sides of each crash bar with the 14mm deep socket. Leave the inner bolts alone. Install only the driver side light bar bracket but only hand-tighten the nuts.

Slide in the light bar from the passenger side to the driver side. Let it rest on the crash bars. Install the passenger side bracket and hand-tighten the nuts. Use the smaller bolts that came with the light bar to attach the light bar to the brackets with a 5mm allen key. I also added two hardened washers (one on each side) but they likely aren’t needed. You may need a second person to hold the light bar as you bolt the light bar to the bracket so that you can lean down to see through the grill to line up the bolts and holes. Ensure that the light bar is pulled all the way forward and rotated to face straight out.

Mount the relay to the bracket by the battery by temporarily removing the bolt with a 10mm socket.

Cut off the spade terminals from the white and black wires from the harness, cut it shorter to length, and use the 14 AWG butt connectors to connect it to the red and black light bar wires (white to red, black to black). Use electrical tape over the connectors. Use electrical tape over the second set of white and black wires from the harness or cut them off if you don't plan to use them (they are for a second light bar).

Temporarily run the two red terminals to the positive battery terminal and the two black terminals to the ground to the right of the relay to test the light bar. Use the attached switch. If it works, disconnect the terminals. If it doesn’t, troubleshoot. The battery terminal requires a12mm socket and the ground requires a 10mm socket.

Reinstall the transmission cooler

Cut off small corners of the wind deflectors with a dremel and then reinstall. This is so that it doesn’t hit the light bar.

Zip tie the wire going from the light bar to the relay in various places to keep it out of the way. There are plenty of places to attach too.

Follow @moe2o4 ’s guide to disassemble the dash panels. Use trim removal tool, 10mm socket, and phillips screwdriver to remove three trim pieces on driver side.

If you're only installing one switch: Remove the blank switch place-holder from the far right. It unclips from the back and pushes to the front.

If you're installing multiple switches: Remove the cubby with a screwdriver.. It unscrews from the back. Screw in the new switch holder.

Cut off the switch from the harness. Cut off a straight piece of a metal hangar. Use the hanger wire to poke a hole in the rubber firewall. Use electrical tape to tape the red, white, and black wires coming from the relay to the hanger. Rub a dab of dish soap over the taped area of the hangar and then pull it through from the interior by pulling on the end of the hangar.

Wire the switch to the harness wires by using the 20 AWG butt connectors. Red harness wire goes to the green switch wire, white harness wire goes to the red 1 (first after green) switch wire, black harness wire goes to the black switch wire. After that, use the 20 AWG quick splice to connect the red 2 (second after green, first from black) switch wire to the green cargo wire (first wire on the first switch from the left). After you connect everything, wrap all the connects in electrical tape.

Reconnect the two two red terminals to the positive battery terminal and the two black terminals to the ground to test the light bar. By default, nothing is lit up. The switch text LED should light up when the interior lights are on. The switch light bar LED should come on when pressed. Test the new switch to make sure it works, that the lighter comes on, and the switch light bar LED should also light up. If it works, proceed. If it doesn’t, troubleshoot.

Ziptie the extra slack going from the relay to the firewall, from the firewall to the battery positive terminal, and from the firewall to the ground terminal. Reinstall the dash panels. Reinstall the grill.

Follow @moe2o4 ’s guide to disassemble the dash panels. Use trim removal tool, 10mm socket, and phillips screwdriver to remove three trim pieces on driver side.

If you're only installing one switch: Remove the blank switch place-holder from the far right. It unclips from the back and pushes to the front.

If you're installing multiple switches: Remove the cubby with a screwdriver.. It unscrews from the back. Screw in the new switch holder.

Push in switches

Use butt connectors (and electrical tape) to connect switch wires to switch

Use quick splice connector (and electrical tape) to connect switch wire to another switch wire for illumination

If you want the rock lights triggered by the dome light signal in addition to the physical switch (approaching vehicle, unlocking vehicle, opening doors, etc

Follow this Toyota guide on removing the a-pillar cover

Ziptie @DSIM relay to one of the factory harnesses

Follow @Volksparts guide on wiring in the @DSIM black wire. Feed @DSIM black wire up behind dash towards a-pillar and use quick splice connector to connect @DSIM black wire to yellow a-pillar wire

Use quick splice connectors to connect @DSIM red wire to switch green wire and @DSIM yellow wire to switch red 1 wire

Reassemble

Lights placement

Middle four lights were placed under each door, rear two lights were under the bumper, all were ziptied to the frame

Front two lights were under the front bumper. I made a paper template of the light by tracing it and used that to drill three holes (two mounting bolts and wire) into the flimsy plastic in the front of the truck under the bumper in front of the wheel well. I then mounted the lights using the two supplied bolts. I accessed the inside of the wheel well to secure the 10mm nut from the wheel well using the 10mm socket to hold the nut and the 5mm alley key to tighted the bolt. You access the wheel well by removing one 10mm bolt with the 10mm socket and one push screw with a flathead screwdriver from inside the wheel well and them pull the plastic aside.

Lights wiring

There are two wires from the relay for each side, each with two leads

Run one wire across back of engine bay facing cab ziptieing to existing harness as you go

Cut off wiring harness leads. Connect additional wire to one of the harness wire leads with butt connectors (and electrical tape, wrapped in wire loom) and run straight down to under truck

Run wire to first light (in wire loom) at the passenger front door ziptieing to existing harness as you go

Three way splice with two butt connectors (one for red positive wire and one for black negative wire). One side has the incoming wire. Other side has rock light wire twisted together with additional wire. I'd strip the wire for both the rock light and outgoing wire and then twist the strands together (do that for both red and black wires respectively). Wrap in electrical tape and then put in wire loom

Repeat above for passenger rear door, passenger rear bumper, driver rear bumper, driver rear door, driver front door (daisy chaining as you go with three way splice at each light, covering wire in wire loom as you go, ziptieing to existing harness as you go)

For the passenger front bumper, connect additional wire (with butt connectors) to the other lead from where you ran across the engine and where you ran the one lead down to under the truck, wrap in wire loom, and fish the wire down to the small opening in the bumper from behind the headlights. Connect the light to the wire and then push all of the extra wire back into the bumper

For the driver front bumper, you can now use the other primary wire coming from the relay. We'll only need the long lead so you can either cut off the extra one in the middle or just cover it electrical tape. Repeat process above for fishing the wire and connecting the light

Rear Lights

Instructions

Same as rock lights with the exception of drilling into the plastic part of the rear bumper with a 1.75" hole saw for the main hole for the light and 3/16" drill bit for the mount screw holes

If you want the new reverse lights to come on with stock reverse signal in addition to physical switch

Follow this EAA guide on how to solder a diode to 2-3 ft of wire and then put wire assembly inside wire loom

Use quick splice connector to connect one end of new wire to middle white wire of trailer harness and other end of new wire to red positive wire of wire leading to the reverse lights

Photos

Footwell Lights

Instructions

Always start with negative battery terminal disconnected (use a 10mm socket) and cover terminal with a rag so it can't make contact.

Follow @moe2o4 ’s guide to disassemble the dash panels. Use trim removal tool, 10mm socket, and phillips screwdriver to remove three trim pieces on driver side.

If your LEDs have a control box, mount it in desired location. I mounted mine using the supplied double-sided tape in the driver footwell area in the bottom right corner.

Use a quick splice connector to connect the red positive wire from the LED control box to the yellow @DSIM wire. I also added extra electrical tape around the plastic connectors with the fuse to ensure it doesn't come disconnected.

Use a quick splice connector to connect the black negative wire from the LED control box to the black wire from the rock light CH4x4 switch.

Pass two of the light bars through the small hole of the carpet under the console to the passenger side.

Run two of the light bars (one for each side) to under the seats while tucking the extra wire up and under the side of the wire console.

Secure light bars in desired locations using zipties and/or double-sided tape. I mounted mine at:

Driver side front: under dash with double-sided tape

Passenger side front: under dash with zipties using holes already in dash

Driver side rear: under front of driver seat using zipties around metal support bar

Passenger side rear: under front of passenger seat using zipties around metal support bar

Relay Holder

Instructions

This is only if your relays don't have the empty tab slot on the back to install onto the relay holder

Drill three holes into relay holder tabs to mount relays with zipties. If you buy relays from an auto parts store, they'll have a slot where the relay holder tabs will slide in. Since I used premade harnesses, they didn't have this

Spray paint over the new holes to avoid rust

Mount relay holder in engine bay

Install relays on relay holder with zipties through hole in the relay and new holes in the relay holder

Hello All!

I have returned from my hiatus. Colorado/Utah was EPIC! I am so impressed with this truck's capabilities.

But now I suppose it is back to work! I have 4 harnesses made, finishing the other 2 tonight.

I will begin taking orders for the SIX. As always, first come first serve by PM.

Testing of DSIM's Dome Light Harness for Rock Lights
...or in my case, for Floor Lights

Alright guys. After installation of DSIM's product I just have to say that this is a nice upgrade. I also appreciate that DSIM supplied the wiring diagram right off the bat. A little bit of background for my situation. I installed these floor lights into my truck a few weeks back using MesoJDM's switch pods to install my switch. I had wired a non ch4x4 switch (bought it off Amazon for $11) and wired it into some floor lights I bought on amazon for about $20. I wired the switch into a 12 volt accessory source on the truck so that I would be able to turn on the floor lights while the truck was on but not accidently leave it on when the truck was off.

Now to the install. First I pulled out my switch panel, pulled back the door rubber, unbolted the A pillar, and pulled off the plastic covering the airbag.

Behind the A-pillar there is the harness for the dome light and tap into the yellow wire using the red tap. The black wire of DSIM's harness connects to this.

Using DSIM's wiring diagram I then had to change my 12 volt source since I had previously had mine connected to an accessory wire. I had another switch I was running straight to the battery with my ditch lights and that wire had a fuse for protection. I wired my green switch wire now into the 12 volt constant along with the red wire coming from DSIM's harness. For you other guys, you are going to obviously have to find your own 12 volt constant. I then had to wire in the yellow wire from DSIMs harness into the second red wire next to the green wire on the switch which connected onto the red wire leading into my floor lights. The ground wire of my floor lights was previously connected to the frame.

After installation, I tested everything out and everything works as should. Whenever the door is approached with my touch sensitive door (or if the door is unlocked with the remote), the dome light turns on and my floor lights come on with the sound of the DSIM's relay clicking. Now, if I want to turn on my floor lights separately while the door is closed I can still push my dash button and the floor lights come on. This is great for driving and seeing the floor. Plus, my cheap floor lights from amazon can blink with music and I also have a remote to change colors of my floor lights if I want to (yeah I know it's cheezy but you got to have a little fun). Now the only issue I see is that if the button is pushed you have to remember that it is now a 12 volt constant and it has to be turned off when leaving the truck. As long as the button isn't pressed though, the floor light will only come on with the dome.

So my general synopsis. Yes this is a worthy upgrade. It reminds me of my old Mercedes which had this setup stock. It is nice to be able to see the floor when I open the door. I may or may not wire in rock lights later on but I am happy with this current setup. Thanks to DSIM for allowing me to test this out.

Just making sure here. The yellow dome wire is a negative wire correct? My understanding is that on Tacoma's the dome is negatively switched. @DSIM I am sure you can confirm.
