Does anyone have the wiring diagram for the electrical circuit for the headlights? I think I have a fried relay. All my fuses are good for the lights but I only have running lights, no headlamps. Also the highbeam light on the dash is stuck on no matter what position I have the headswitch in. The truck is an 03 F-350 Crew Cab Short bed with the 7.3L. Any help would be greating appreciated!
