Can anyone tell me where i might find a wiring diagram free for my 1993 F150. I'm trying to avoid replacing the headlight switch and if I can trace the proper wires, maybe i'll find a problem with them first. Please help me out.

 

Buy a cheap Haynes manual at a parts store, their wiring diagrams aren't bad. Factory manuals are the best, but are quite a bit more pricey.

 

Here are some freebies. But they are not the greatest.
