as the title states has anyone ran kc lights or simalar offroad lights to there fog light harness?

are there any problems with doing it this way?

 

well......idk. you need 14ga for KC's 100w and up. So stock 22ga wire or whatever won't work. There is threads showing how to wire your stock foglight switch to power on aftermarket lighting...

 

you can use the foglight switch, but you should always wire all aftermarket electrical stuff with its own harness, fuse, relay, etc.

#2 is the schematic you will use

 

As long as you only wire 2 lights through one circuit you will not need a relay. Use 14 gauge wire and yourll be fine. For my lights I have 2-150W lights on each of 2 circuits. I have never had a problem with it and ive ran them alot.
