I'm finally about to break down an take my front bumper modeling off for the extra clearance. I don't want the stock fog lights just hanging down there so they are coming off. I have some hella 500ff 55w lights sitting around that I've been putting off installing for a while. Can I use the factory wiring an switch on the hellas? Any information on color codes for the wires. Thanks in advanced.

You could, but I would only use the factory wiring as the Switching circuit for the relay that the lights would run off.

The factory fog lamp harness is already wired up with a relay. Go to great lakes XJ and download the FSM for your truck it has the wiring diagram in it for the fogs. From the switch the violet/white wire is your power, blk-ground, brown/white-to relay.

Yes, it is, but that entire circuit is way too light a gage wire for atermarket lighting. Use it ONLY to switch on ADD-ON relay which will supply the power to the new lights.

I used the factory wiring for a set of KC's, they've been on there for a few years now with zero problems. They also get used quite a bit.

My XJ also has a set of PIAA fogs running on the factory wiring and I use them everyday with no issues.

Finally got my bumper on an mounted the lights. I'm wiring them up tomorrow. Gonna cut the factory connector off. Anybody know the colors of the hot an ground wires on that end? I'm a wiring retard so break it down Barney style for me

the one that sparks on the bumper is the hot wire
