2003 TJ - Moving fog light switch from MFS to toggle switch

My Multi Function Switch crapped out and now my fog lights are stuck on even when the Jeep is off. I pulled the fuse for a short term fix, but would really like to set this up with a toggle switch like they had on the earlier model TJ's. I have a strong dislike for Jeep's MFS and would rather bypass it then replace it. I like the toggle better anyway.

I saw in another post where some one re-wired thier fog lights from the MFS to a switch in the dash. They didn't give any detail though. Is there a thread out there that details how to do this? What wires to splice and where? I must be search challenged b/c I could not find anything out there... Just as good would be if some one could post that info here... Pictures would be especially helpful, but I'll take what ever help I can get. Thanks!

When you take off the column cover you will see a lot of wires with a large grey plug. One of the wires in this plug is white with an orange tracer. Take this wire from the connector and run it to your new toggle. Then connect the other pole of the switch to any ignition switched circuit i.e 12v when the key is on, or off if you prefer your lights to work with the key off. After all its just the trigger side of the relay you have to power. Then all of your factory stuff will still work, i.e. dash indicator lights. Hope this helps.

Sorry, I'm pretty unskilled when it comes to electrical know-how - What wires, specifically, can I splice this end of the rocker panel to in order to have it switched or not switched? Like the radio power or something? Or could I jam a fuse and a wire into a slot on the behind the glove box panel? Any photos?

Thanks

I'm trying to migrate control of the factory fog lights from the MFS to a rocker panel switch. I remove the steering cover on the steering column, and the orange traced wire on the MFS goes into one prong of the rocker. The other end of the rocker connects to a switched or unswitched power source. My question is, where do I locate a source of either kind? Basically, just wondering where I can find a source of switched or unswitched power in the cab? Thanks!

Easiest place i found is behind the radio. I have an aftermarket head unit, so i just use the switched wire on that harness for all my light switches (have like 4 all piggybacked off the same one, no issues). I would advise against using constant, as that is how i initially had my lights wired up, and on two different occasions, i had accidentally switched a pair on and not noticed, and came back to the jeep with not only a dead battery, but melted lights and covers as well. After the second time i rewired them to the ignition!

Cyber,

what do you think about maybe using this add-a-circuit and plugging into a switched circuit behind the glove box?
