    I'm looking for some help with a lighting problem.

    I have a Diamond installed on a 2001 Ford Super Duty, it has the old style lights ( NOT SABER LIGHTS) I installed the harness and switch, I turned on the lights and found that the left side lights only worked on high beam, and the right truck headlamp was lit very dimmly when I switched back to the truck lights . I discovered the plugs were badly corroded, so I replaced them matching up all the wires. The left headlamp and turn signal lamps worked great, but I still had a dim truck headlamp on the right side when I switched back . I disconnected the adapters and plugged the OEM headlamp plugs back on and all the lights on the truck worked fine. I'm thinking there has to be a bad ground or a cross fed wire, can anyone help? How about a headlamp wiring diagram? anyone?

    Thanks in advance

    Wiring Diagram


    Looks like a twelve pin switch, this harness came out of a 2000 F350 and I installed it into a 2001 F350, so I'm 99% sure I have the correct adapters.

    Thanks for your help!!!!!

    That's definitely a bad ground. There might be another bad connector, corroded wiring (where insulation chaffed) or it might be the ground itself.
    Just trace the wires and see what you have, you shouldn't need a wiring diagram for this.
