Fog light wiring question for my LJ

yj_ryn · 06-17-2006, 05:37 AM

If I have the stock fog lights on my LJ and I buy some KC lights, can I tap into the stock wiring so then all four lights could be turned on at the same time from the stock switch on the turn signal?

Will this affect my output from the stock fog lights? I thought this would be pretty easy, but I wanted to check with the jeep gurus first.

Ive replace my stock fog lights for KC and have been using the stock wiring for some time now. Ive had zero problems with running 100w bulbs for hours. I am not what you call a guru i just sort of did it before i joined the forum and have yet to have any problems.

now this is somthing you can do that way you can put you KC's on the windshied.

I wouldn'r recommend running the power from the existing lights to 2 additional lights directly. Almost certainly the wires and switch isn't sized to run 4 lights instead of two.
Now you could power a relay from the existing wiring, that has very low amp draw to switch the new set of lights on, with the main power for the new lights coming from a fused line from the battery.
If you want to turn them on with the factory switch, this is what I would consider.

Have you by chance run across a good write up on this? I'm looking to replace my stock fogs with a set of Lightforce 240's and would like to use the factory switch. I assume it's just a matter of wiring up the lights using the new harness and taping into the factory wire just to kick them on?
