When you say that they are wired together on the factory harness, do you mean they are sharing the same Hot wire as the Main headlights? I tried looking for a good wiring diagram but only found bits and pieces....
Thank you all for your feedback, It is what makes the Jeep community great
It could be the difference in the model years....but the part about "tucked up and zip tied on each side" makes me question if it already had been jacked around by PO. On my '04 that, I purchased in '04, the wire loom from fuse box under the hood, runs across the top of the firewall, and along the driver's side fender. And than the wiring when it reaches the drivers side headlight, turn signal, fog light area.
I would imagine Jeep did this to conserve wire only about 4 feet of wire but 4 feet x three lights, times a few 100,000 Jeeps...WOW!
The being wired together......IDK the exact correct terms, or exactly how it is done, but there is a relay that allows the factory fog wiring to only be on when the headlights are on low beam.
I think your original post said you had your HIGHBEAMS and FOGS on at the same time. While I have that ability now, and know that the "mod" has been discussed on here, I don't know if the factory wiring is "heavt enough" to carry that kinda of a load.....especially with the upgraded fogs. And IMO electrical will do some "funny things" when we start putting "too much juice", to smaller gauge wires.
IMO I would wire those big Hella's on their own dedicated circuit, and hope there is no permanent damage to the headlight wiring.
Seperate/ rocker toggle switch, relays and it's own complete harness. The factory wiring is just not up to the job for that big of a draw all the time.
I would do the same thing for the Slim lights, but honestly, I have the KC fog replacements, the headlight upgrade, and the slim lights myself, and each on its own circuit, headlights on factory circuit no other lights tied in.
But I rarely NEED all of them. I sometimes use slim lights without the fogs with headlights, but never have I needed all 6!!!
