Forgive my stupid questions:
- are they wired-in "before" or "after" the Headlamp Terminal Blocks on each inner fender?
- one relay or two or three/four relays for front lights on an A-D truck?
- one relay for headlamps and one front parking lamps; and/or, one (each) for both sides?
- do people use them for 6v rear lamp/lamps?
I'll try cleaning grounding screws/bolt-points, and maybe then try grounding wires; but, after that . . . .
