What color is the low-beam wire?
Does anyone know which color wire to tap to trigger a relay from the low-beam headlight circuit? I am installing fog lights on a relay. In my state (PA) they can only be run with the low-beam headlights--so I want to trigger the relay off of the low-beam circuit. The wiring diagram is almost unreadable but it seems there are Y (yellow) and B/Bl (black w/blue tracer) wires to both headlights, along with B/W(black w/white tracer) which I presume is the ground. I'm trying to figure out if the low-beam lead is the Y or the B/Bl . Thanks.
