Hello, my name is***** is a pretty advanced setup as far as wiring goes for headlights so lets start by checking to see if one of the pins at headlamp grounding relay have good ground, it should have ground at all times. Let me know, thanks.
Correct. One of the pins should have constant ground, if not we will check ground locations. Let me know. Thanks.
No problem, let me know when you get a chance to do test and we will go from there. Thanks again and have a good evening.
