Hey Guys,

I have this wiring diagram and I don't see a headlight relay just a lighting module like Steve W. said run some tests using a test light to find where you are loosing power.

Please run some tests and get back to us so we can continue helping you.

Best, Ken

There is no headlight relay. Here is a headlight wiring diagram to show you how the system works and a guide to help you check the wiring:
