I bought my 2006 Wrangler without factory fog lights. Shortly after, I bought some KC lights and wanted to throw them on. I did a sloppy but functional job.
Recently while poking around under my fenders I found that my jeep was wired for factory lights. I decided to remove my sloppy wiring job and tap into the factory wires. After searching on the interet I found a lot of people had the same questions but the answers were scattered and lacked detail. So after 4 hours of tracing/testing wires I found the answers I was looking for and have decided to share. I hope this is helpful to anyone with the same questions I had.
The open connection points I found [one under each fender - near side marker lights] White/Orange wire comes from the fog light relay and the black is a ground.
Then I looked into my fuse box and saw I was missing the Fog Light relay [35] but did have the fuse [19][Under Hood forward of Battery]
I spent some time and investigated these relay and fuse slots.
I traced two wires to the steering column, the white/yellow wire from the fog lamp relay [slot 35] and a red/green wire from the fog lamp fuse [slot 19] - After taking apart the plastic that surrounds the column I found these wires leading into a large plastic clip located behind the hazard light switch.
I removed the two wires related to fog lights and hooked them up to a rocker toggle switch. The Red/Green wire comes from the Fog Light Fuse mentioned above and brings power to the switch and the White/Yellow wire brings power from the switch to the Fog Light Relay [See relay image above - note where the white/yellow wire enters the relay housing.]
*Be careful at this point as there are a couple of wires entering this clip with very similar colors. Notice on my picture I am choosing the white/yellow paired with the red/green. These two wires are located next to each other and one space away from the white/green and green/white [hi beam] wires. There is another wire on the "top" of this clip that is cream/gold colored and looks very much like the white and yellow.
And heres my toggle mounted on the dash behind my light control stick. [Please ignore the dirt] Toggle has three wires - ground - power in [red/green] - power out [white/yellow]
I was surprised to see that my instrument panel now illuminates a green fog light icon in the top left when I turn my fog lights on. I also now have the often bypassed feature [thanks to my fog light relay] of not being able to use my fog lights while hi beams are active. We'll see how long I keep this feature before bypassing it.
Let me know if there are any questions, or if you forsee any problems with this set up. I hope this information is helpful.
[Note: The same relay can be used that is found in the Starter, Fuel Pump and Horn sockets. AC Delco makes a version for less than $20]
