Headlight switch wiring diagram
#1
#2
I haven't received a response for my post. Maybe I wasn't clear on what I needed so I posted a couple of pictures. Basically, I need to know what each wire does (powers) below for a '97 model.
Reason is I read the article here on the boards titled "Whiter Whites, Brighter Brights" (where you wire the headlights to the battery for improved light output) and thinking about doing the modification. However, I don't want to cut the factory harness up. If possible I'd remove the wires at the headlight switch plug and run the new wires from there to the relays. Hopefully that makes sense. Automotive electrical isn't my strong point.
