Fog Lights

OcracokeOBX · 02-07-2010, 07:42 PM

Finally sick of having to finagle my fog light switch to get fog lights rockin, am bypassing that. I have a switch pre-installed in my Jeep from when I had subs, so that switch currently has nothing connected to it. Any way to run the factory fog lights to my switch?

sure you can. look up the diagram and then use a relay to hook the output from the OEM switch to the 87 pin on the relay. then send the 30 pin to a high amp 12v or to the Batt. then tap 86 to the 12v as well and 85 to one side of your switch and the other side of your switch to ground. use a fuse of appropriate size on all 12v lines. a 5 amp on the 86 pin of the relay is planty good enough, a 20 amp on the 30 pin should be good depending on what lights your running

Do you think you could write that in English now?

Im wiring up some fog lights as well, but Im not very good with electrical terms.

I understand the diagrams though.

You can't run the power straight to the switch, you risk burning out stuff. What a relay does is keep the main amount of power from traveling through the switch.

jerman75....if I ever find myself in a foggy situation and avoid hitting something because I can actually use my fog lights, I'm sending you a fruit basket
