just finished up the wiring on my 06 Wrangler

Just finished up the wiring on my 06 Wrangler. I went with using 4 Roadmaster diodes. Instead of installing them back at the tail lights, I chose to install them under the drivers door sill. All the wires going to the back lights and hard top run right there and there was plenty of wire length to work with.

I started with 14/3 sjoow wire and used a phillips screwdriver to poke a hole in the rubber grommet that the main harness goes through at the firewall. I routed the 14/3 throught that hole, then up and around the harness underneath the dash. Then ran it along side the harness that runs under the drivers door sill. After I found out which wires were what by looking at the rear tail lights, I cut all 4 wires (2 at a time) and staggered the cuts so that I could mount the diodes just under the black plastic cover that runs under the door sill.

Then I ran the 14/3 wire up under the hood alongside the factory harness on the drivers side, them down alongside the radiator and to the center of the Wrangler to the mounting studs that are on the BX1120 Blue Ox baseplate.

The hardest part was tring to figure out which wires were the correct ones in the 20+ wires there under the door sill. I found a wire diagram for a 2003 on line but it said the tail light wire color was black with a yellow stripe. Well there wasn't any wire that color. I finally figured out that the tail lights were white with a yellow stripe, the left turn signal/brake wire color is dark green with a red stripe and the right turn signal/brake wire color is brown with a red stripe.

Overall it wasn't too hard.
