Leer Cap Wiring Help

Hey everyone! I just bought a used Leer 100xr for my new to me tacoma. Its got a third brake light and an LED interior light that I'd like to get wired up.

I'd like to get the interior LED hardwired so that it can come on even when the truck is off so that I can access my gear and sleep in the back of the truck.

Any suggestions? I was looking at Leer's 7 way harness but I feel like spending 80 bucks on that is entirely unnecessary.

Thanks!

The place where I got my shell did all the of lights with the install.
But they went direct to battery for the LED strip. Not sure how he did the third brake. Most likely tapped into the tail light.
I think @ERMB wired his up himself.
@Blais03 may have some good ideas too.

 

For the Brake light, just tap into the wiring behind the driver tail light. Use some kind of quick connect so you can remove your cap if needed.

For the interior light, you'll need to run a hot from the battery and then ground it.

 

Thanks I knew you could offer some help.

 

awesome! thanks y'all. What tail light wires do I need to tap into?

 

it has a little 5 plug harness on it. guess i'll need to get a battery and do some figurin on it then maybe i'll my own harness

 

Find the wires going to the brake light bulb. Use a tester to determine which is hot and which is ground. Splice a wire into the hot that will connect to the hot wire going into the brake light. Same for the ground.

 

For the 3rd break light I tied into the tail light in the bed. I think it was a brown and white wire. Not 100% sure. For the led I ran a switch to the dash then a hot wire all the way back to a led strip I ran around the bed not to the cap because the single cap light did not give me enough light.

 

Tie it into the trailer wiring. itll probably be the easiest spot to reach without pulling tailights out and all that.

 

Update: did the wiring on the cap today and it turned out great!

Got a 4 ft 4 pin extension and split it in half so I had both the male and female ends, ran a hot wire to the battery with an inline fuse to the light, and tied in a wire from the driver's tail light for the third brake light and it's all done!

 

Here it is!

 

Out of the way, easily accessible, and easily removable.

 

My wiring harness got pulled out / destroyed recently while removing my Leer cap. The wiring harness was unplugged but got caught on something. I got another standard 4 prong wiring harness and installed it today. I took some pics that I figured someone will find useful someday.

On my 2010:
Red & white connects to green & black. (the red/white wire has the light blue connector)
Red connects to green.
Black connects to black & white.


(I wrapped it all in electrical tape after taking this pic)

 

Dielectric grease if your friend with splice taps and trailer connectors. The tape will shrink... The glue fail.. sometimes the tape gets nasty after time

 

No black and green in my wiring harness

 

I just made my own harness to a switch by the driver's seat

 

Do you have a picture of your reverse and brake lights spliced in behind your tail light?

 

For those cap lights I installed? They're not spliced into anything.
