This is related to my headlight/running light question below. Where can I find a detailed schematic of the headlight/running light system. My Haynes manual is good for the small house with the moon door. I found relays under the top of the dash, pulled the relays and the lights go out, the main switch is disconnected, but if I plug those relays back in the lights come on. Checking them with a multimeter and they appear OK, so power is coming from some other place. Hair is turning very grey now.

I guess no one provides schematics for newer vehicles, man do I miss the old simple wiring in the cars and trucks. Stopped by the local Ford dealership today, they didn't have a clue and I have stumped this panel.

got it, the RAP module had shorted and was providing ground.
