    Hey guys! New to the site! I gotta headlight wiring problem! I found the High-beam and low-beam wires on the inner fender of my 1993 gmc pickup that I just bought a older fisher plow system with the under hood hydraulics. I also got the harness as well. I got everything wired up and turned my headlights on and ALL headlights including the truck came on. I hit the toggle switch and they ALL went off except the parking lights! Its gotta be something simple! Thanks for any help! :confused:
