Hey guys! I am trying to find the harness for the stock fog lights. I have been told that they are under the bumper, but i cant find them. Could someone please lead me in the right direction? thanks for your help!!

 

Are you adding fogs or do you already have them? Take the air dam off.

it didn't come with fog lights stock so I have added the stock bumper with stock fogs, but right now they arent functional. I would love to get them working. I was gonna try to just run a toggle from the stock wiring if it was there. The more i read the more i think im gonna have to do...lol
Thanks!

 

I am having the same problem. The dealership told me if they did it they would just wire it to the battery and run a relay and switch into the cab. I told them I would rather have it work as designed on the stock Rubicons. I even went and bought a new multi-switch for my steering column.

Another dealership told me the wiring harness is there on the X, just behind the headlights but I couldn't find it. They also mentioned that I would need to bring the vehicle in so they can update the vehicle's computer to register the fogs and activate the multi-switch. That part sounds reasonable, but I still couldn't find the wires behind the headlights. I would rather do it myself as I don't want the fogs jury rigged onto a switch.

I am running out of options though.

The wiring harness is not there. You will find a wire loom coming across the front bumper, but this is NOT the foglight wiring! It is the ESP/ABS wire, so don't cut into it.
I like the approach this member took in this thread https://www.jk-forum.com/forums/show...g+light+wiring . Make your own harness and tap into the side marker as the switch for the relay. This will keep your foglights on even if you're on highbeam.

 

the way I did it was I went to autozone and got some sockets that fit those H10's or whatever comes stock. I think they were actually for 9005 bulbs, but they work fine. Then I ran a wire from my battery to a fuse to a relay then a wire from the relay to the fogs. I ran a wire from my parking lights to the trigger on the relay. Then I ran a ground to the frame. I wrapped all the wires in plastic wire loom and zip tied it in sections. I took 2 of the weatherproof wire connectors and soldered them on the end and then made up a "harness" with the new sockets and some wire loom and zip ties for the front as well. I put a little elec connector protector on the connector ends and then heat shrinked them after I connected them. I don't have a switch my fogs just come on with the parking lights or head lights. They work of course with the lights on dim or bright.

here is the "harness" I wired up for the lights:

 

BigBlueJK - I like your idea but I don't know if I would want my fogs on all the time like that. I still wish I could get the information on how to wire it to the Jeep's multi-switch.

I can't believe that with all the experts and mechanics out there that no one has ever come across this problem before and come up with an answer other than to run a relay to a new rocker switch.

If anyone has six degrees of separation with an engineer or designer at Chrysler, I would love to chat with them...

Thanks,
Still going crazy

 

Not trying to jack the thread but does anyone know the wattage for stock fog lghts

 

Did you buy the fog installation kit from Mopar? It has the multi-switch, wiring and everything else needed to get you the stock look. It's part #82211870. You can get it at Quadratec or others. You could probably find installation instructions online if you don't want to buy the kit (sounds like you already have some parts).
