I plan on installing a set of seperate fog lights. Can I simply use the factory wires by lenghtening them left and right? If so, what are the wire colors in the harness that goes into the headlight assembly? Option 2 would be use the drivers side factory fog light power wire as a signal wire to power a relay for the new lights. Still need that wire color too. Thanks! My car is a 2003 G35 coupe, 6 speed car.

 

I know this is old, but there are remote control switches for fogs. I would look into that.
