how to wire bed lamps:

[unholycumulus]

I decided to do a full pictorial write-up on how to install bed mounted lights in our second gen Tacomas. Hope someone finds it useful or somewhat inspirational so they can trust themselves to do it too. It took minimal effort and was done in a matter of hours. I’m a SERIOUS novice when it comes to electrical, so if I can do it anyone can. I’m also a picture whore, so I took MORE than needed.. I figure it might help. Enjoy.
------------------
First step is to find a set of lights. I went to Harbor Freight and found a set of those crappy little fog/driving lamps that you see ricers use all the time. Cost about $11 bucks. This set came with a full wiring harness and switch – so I’m more than impressed. Harbor Freight… I think I love you…



I then took the side pockets out of the truck. They disconnect very easily without tools. Just grab the inside of the pocket and push upward, then pull in a downward-out motion. They snap right out. Play with them for a second, it’ll make sense. Inside of these is where I will mount the fog/driving lamps. I then took out the driver side lockable pocket. They come out with a metric hex tool. This is where I will mount my switch for the lights. Soon I’ll mount another in unison for the interior so I can operate either switch to work independently no mattering on if one was off or on; but that’s at a later date.

I first mounted the lights by drilling a hole on the top of the side pocket. One hole on the top for mounting and one on the top for wiring. I chose to do one hole for one bolt rather than one for each side of the bracket so I can rotate the lamp side to side to distribute light accordingly.. or maybe aim all the way back for tailgating? Who knows. Why limit yourself when you don’t need to



I then mounted the switch on the inside of the lockable pocket. This switch came with a sticky that made life a bit easier for mounting. I drilled one hole on the top of the pocket again for wiring. I’m sure it’s fairly obvious, but in case you wondered; I drill holes on the top of the pockets for the wiring instead of side or bottom to eliminate any fatigue to the wires when it comes to water and its pesky drainage.










Final product so far (I put the wires together just to show you how they will end up):





Now is time to lay it all out.


Inside the passenger side side pocket’s mounting hole, let’s use what Toyota seemed to lay out for us: a perfectly located ground!





I will start on the passenger side. Hook your black grounding wire from the perfectly located grounding bolt to your black grounding wire coming out of the top of the passenger side pocket. Then hook up your (in my case white) hot lead and send it down towards the back of the truck. I found this was the easiest way to loop it around.







Now, get under the truck and thread it along in a way that makes sense. And it will. You want it to pop out where the lockable pocket is.



This will make it easier to run the passenger side lamp’s wire from the lockable pocket’s installation point to your driver’s side side pocket by being able to sit in the bed of the truck and loop it over. Connect the hot (white) wire to the side pocket’s hot (white) wire.



Now ground out your black wire exactly the same way you did in the passenger side pocket:



Your two lamps are now connected together. It is time to send the wire over that will attach to the switch. Simply hand it over to the lockable pocket’s installation hole.



And snap it in place.



I then zip-tied the loose wire together so it won’t dangle or snag or anything. This is optional, but I feel it’s necessary. Your next step (not pictured) will be to connect a wire that will run from the switch to the battery (or your constant hot lead). This hooks directly to your switch (red wire)



Install your box. You’re done here.



(For some installations, if they don’t have their own wiring harness included, you will need to use a relay. A relay keeps the power for the lamps from going through the switch itself. It’s basically a switch for your switch so you don’t overheat that plastic switch, or make it so hot you can’t touch it! Look it up if you have any questions on how to use/wire in a relay – for this install, the switch I am using is its own relay.)

Next will be to send that wire from the switch to the nearest constant hot lead. This is where I’m fuzzy. I want a constant hot so I can operate this newly integrated option even when the truck is off or locked or anything. I don’t believe there are any constant hot wires running to the bed, so I just sent my wire directly to my battery using an eye hook. I will research a bit and redo it at some point, but this will work.



My wiring harness had a built in fusible link. MAKE SURE to fuse this section of wire if you’re as not lucky with your harness! You want to always have yourself fused somewhere when dealing with this sort of project as to not blow up your bulbs or catch anything on fire.
Use 16 (or more) gauge wire (no less) when running any grounds or constant hots.

The final product:






I’ve tried it at night and loved it! I also aimed them a bit downward and one angled towards the cab and one towards the tailgate. This distributed the light very evenly. I hope this write-up helps someone somehow.

Nice! It makes good use of those worthless cubby holes in the bed. I may have to do this next spring. Good write-up. Thanks

[gavonder]

Very cool! Thanks for the effort.

good write up !
suggestion
say put the fuse as close to the battery ( source) as possible
if you have any wire chafing, or pinched wire the fuse will blow before any damage can be done, if you put it back by the lights then by the time the fuse blows the wire is totally melted ;-D

do you know the wattage of the lamps
think 55w each?
if so total current is about 8.5 amps so a 10 amp fuse should work just fine

[unholycumulus]

Thanks for the complement guys. It was a very easy install and does make good use of those totally useless cubby holes (seriously.. why did Toyota even put them there..?)

phantom: very good input, i do hope if anyone uses this as a guide they take your advice into consideration.

I fused with a 10 amp. I didn't catch the wattage on the lamps, but have messed with them plenty and no blow-out yet. They're halogen if that helps.


EDIT! Just wanted to state that double cabs do not have the grounding post the way i showed in the pictures. You'll have to search out your own ground.

My guess would be 35 watt. I have a similar set on my motorcycle. Good write up.

i had looked at the harbor freight page and h3 55 w each
so 110 w total

from the page

Comes as a pair. 55 watt, H3 halogen bulbs;

ITEM 46908-1VGA

[unholycumulus]

Yup, here they are: http://www.harborfreight.com/cpi/cta...emnumber=46908

A $12.99 DIY install. Not bad.

EDIT 02/26/2009: HF lowered the price of the lamps to $9.99!

EDIT 06/06/2009: HF raised the price back to $12.99..

[unholycumulus]

this morning i went to just play with the lights.. see if they still work, and the passenger side one did not! I found that the ground wire didn't have a good connection with the eye hook to complete that ground. i replaced the eye hook and it worked fine.

if you're thinking of getting the same lights, make sure and check your wires (it is $12.99 afterall)

[Ghost96Romeo]

Great job man.... I'm considering a similar setup, and now I have your write up to follow for ideas. Thanks

[longbow]

Great write up, going to use it for my 'guide' when the time comes.

[neslerrah]

Great write up. I will be doing this mod myself. Thanks for the links and pictures!

[socalman22]

Nice write up!

[dizrick]

Nice write up. I have been thinking about doing something like this and now you went and made it easy for me. Good Job!

helps.

I like them - I keep my keys in them when I'm in a reasonably safe area (like on a construction site) but don't want to carry them with me. Keeps them out of the weather. But your mod is a good use for them.

Isn't there a constant hot that goes to the trailer electrics (for those that have the tow package)?

[unholycumulus]

i'm glad some of you will use this as a guide! That's awesome =D - thanks for the complements everyone.

petersharp - i usually use the gas cap compartment when i need to hide my key (usually when surfing)! I did a bit of research and i believe there is a constant hot for the tow hitch wiring.. once i find it i'll splice into that and save all my wire for another project!

[nvdeserted]

Excellent install. I sometimes have a bed/cargo rig that sits at about the bottom of the cubbies and I think that having the light there would be opposite for my needs and I would probably set my sleeping bag on fire HA! But nice work!

[santacruzer]

When I had the camper shell installed on my '09 TRD Off-Road DC, I asked them to pigtail a "hot" wire into the bed (driver side tail light area) as they were wiring the shell. It's a separate new wire, fused at the battery, and I just today wired in a hot 12v outlet just above that locking cubby box on the driver side. I now have AC and DC in the bed. I'll splice into that 12v hot circuit again later on and wire in some bed lights just as you've done! I'll likely switch them from near the 12v outlet.

I also removed the doors from the left and right rear cubbys, and sealed up all the holes, drains included. If you're on dusty roads, dust just blows right in the drain holes and makes a mess. Not a problem...unless you have a shell, then it's a PITA.

I've seen setups like that before. I'll add it to the cheap/free mod thread since it's another option for people, and a good detailed writeup. Personally, I don't like 2 fog/driving lights aimed at my eyes when I open the tailgate. That's why I went for a more distributed lighting system.

piercedtiger - I’m honored, thank you! What’s nice about this install is the lights are adjustable up down and side to side; so I’ve aimed them low and the lights surprisingly aren’t in the way. It came out nicely. Come by SD sometime and i'll show you BUT i did read your write-up which is what inspired me to do my version.

Santacruzer – I’d love to see your mods, make a post and let’s see your work!

Again thanks for the complements all. Its fun doing this stuff when it’s appreciated. I will continue to write up my installs for you all.
