This is a simple extension of wires. I have rerouted and protected them from the environs.
Anyone who has a swing out tire carrier knows the frustrations of the 3rd brake light wiring. I installed the LoD Shorty with all the goodies including the 3rd brake light bracket, but the wiring is one thing that was not mentioned in the install. Here’s my fix and maybe it will help someone else.
1 out of 5 wrenches
Phillips Screw Driver
12’-˝” Wire Loom
30’- 16ga Wire
4- 16ga Butt connecters
4- Heat shrink tubes
10- Zip ties
*Disconnect the battery when working with anything electrical on your JK.*
-Remove the 2 plastic trim pieces on the tailgate.
The long horizontal one has snap tabs on the bottom, and hooks reaching up, so pull the bottom straight out.
The vertical one has snap tabs on the inner side and hooks on the outside, so pull from the center line of the jeep first and swing it out towards the driver’s taillight.
-Remove the grommet holding the wiring to the 3rd brake light.
You can cut the wiring off on both sides of this grommet.
Apply a small dab of black silicone to both sides of the grommet and set aside for drying.
-Remove the factory mesh wrapped around the wiring to the 3rd brake light.
Set aside this will be reused.
-From inside the tailgate’s large hole
Note the color coding of your wiring (#1-black, #2-white w/orange strip).
The 2010 JK’s have a diode that give the 3rd brake light a triple flash when applied. I like this function and kept the diode in place. In the photo below you want to connect to the far upper left wiring, which was trimmed at the tailgate grommet
-Connect 15’ of wire to each of the connections inside the tailgate.
I used heat shrink butt connectors and covered them in heat shrink.
Note which wire is which if running the same color wiring, simply placing black tape on both ends of the same piece of wire will help. Running different color wiring will help even more, but is not necessary if you mark the wires.
-Run the wiring following the factory wiring across the tailgate to the passenger side.
I reused the factory mesh fromt the 3rd brake light as protection along the rear tailgate. Loosely zip tie the wiring to the factory zipties.
-Pull up the carpet on the passenger side upper fender.
Here you will expose a grommet. Punch 2 holes through the grommet, remove grommet, and run a wire though each hole.
-Under the passenger side fender is a hunk of foam. Push up, twist, and pull out.
Note the orientation for reinstall. This area will expose the inner fender well and the wiring will run down though that to a small hole in the bottom of the fender. Pull the wiring through the small hole.
-Run the wiring under the fender directly to the hinge point of your tire carrier.
