Replacing Factory Fog lights in a TJ with offroad/driving lights

Could you use the existing wiring for the factory fogs to hook up other lights, or would you need to run new wiring to them? I'm replacing my bumpers, and thinking about ditching the fogs for something better. I was thinking some of the slim line KC driving lights in their place.

If the new lights don't have too much power its fine, but a lot of aftermarket lights draw more than the stock harness can handle. In that case you want to use the harness that comes with the aftermarket lights to get power to them but you have the option of still using the stock switch by using the stock harness as the signal wire for the relay.

These say 55W, and I also saw a pair of 55W KC Replacement fog lights that attach into the existing wiring for the TJ fogs. So I'm assuming that if the 55W fog replacements are fine, these would be as well.

Yes, I believe 55W is what the stock harness is rated for.

As stated above, stock lights are 55w, so anything close is safe.

If you wanted to go bigger, but still use stock switch, etc. just add a relay off the wiring at the fender.

Using the stock wiring to pull-in the relay which provides "heavier" power to the new lights.

If the replacements are 55w you are ok. If they are 100w use at least 12awg. Personally I would use 10 AWG for 100w lights. Better to have too big of wire than too small. Bigger wire will let them be as bright as they can possibly be.

Has anyone used the cheap Harbor Freight lights?

http://www.harborfreight.com/6-inch-...tem-95811.html

Some of the reviews mentioned rust problems, but most just mentioned painting or putting a spray on clearcoat to solve that problem. After taking my factory fogs off the old bumper, I just didn't feel like putting those old beat up lights back on my new bumper.

So I went the cheap harbor freight route for now. Just bought some wire, conduit, and clipped the factory fog connector off and wired them in. And while I was at it I did the relay mod so that they will operate on high beams as well.

I also have a similar problem as Bhamshooter. I want to replace my factory fog lights on my 2004 wrangler tj to match my KC hilites on my windshield. I found a good pair by KC that say they plug into the existing harness as you guys mentioned above. http://www.quadratec.com/products/97047_120X_PG.htm. I was about to buy these pair until i decided to check my jeep to see if i could find the wiring harness of the original fog lights. I check the passenger side fog light and i dont see a connector for the fog light. Instead i only see a ground wire. Wires then go through the bumper and attach to the wires of the fog light on the drivers side and then up and through the firewall. I am wondering if i can still use these replacement KC lights? The switch for these lights is an aux switch on the dash center console instead of the steering column. So im thinking the previous owner might have added the OEM factory set after? Any advice would be helpful. Thanks!

If there's an aftermarket switch that is running the fogs then you probably didn't have them from the factory. Just tap into the wiring directly behind the existing lights and wire your new KC's into there. It may not be plug and play like you want, and heck it may even be cheaper to order some KC's that are 55W without the connectors and just splice into the existing wiring.

So about three weeks after I installed these, my better half finally noticed them. She said, for lack of better words, that they looked bad and cheap. I told her they were cheap, but that they looked identical to the KC Hilites I had on my old Jeep:



She then told me she never liked the way those looked, which is odd considering this was 15 years ago. Oh well.

But I handed her my latest Q'tec catalog and told her to knock herself out and that Christmas wasn't that far away!!
