OK so I've been asked here and on other forums for a little more info on my install.
So here's a shot of the bottom of the relocated third brake light with the LEDs stuck to the bottom.
So after hours in autoparts stores, and online looking for a 2 wire quick disconnect, it suddenly came to me when I removed the old plate bracket, that I could just reuse that one.
Next I ran the wires from the LED/Disconnect through the tailgate following the third brake light wireing (I also ran my CB coax this way).
Here is the opening inside the tailgate, closest to the latch. With the cover off, you can reach in a grab the wires when they pass through the outer wall.
The wires do a quick U-turn and pop inside the tailgate under the long rectangular plastic cover. (The wires hanging are the wires from the LEDs)
The wires were then ziptied to the main batch of wires and neatly run behind the nylon cover to the rear passanger side rollbar.
In that corner, you'll find a rubber cover with the wires that run from the front of the Jeep to the passanger side tail lamp. Now you can tap into the wires here, but I needed to find out which ones were the wires I needed, so I ran the wires from the LED to the tail lamp.
Here I unscrewed two screws on the inside/left side of the tail lamp to remove the tail lamp. The two outer/right scews are just there to hold the lens to the plastic body of the tail lamp. You only need to remove these to get inside the tail lamp.
There are four wires running into the park/turning lamps. The ones you need are the black (ground) and white with a purple stripe (park light).
Like I said, you can find those two wires up top, but since I was already there, I tapped into the wires by the tail lamp.
