Not a stupid question at all, Roscoe. I'll probably turn out to be the only dummy here. I did some searching through the archives before I hollered for help and I found quite a bit of discussion on relays. Since my harness came with literally everything including the fusebox in a labelled , step by step connection package custom made for a Unique with my engine, I assumed that any necessary relays, fuses, etc would already be there. I looked but cannot find a relay for the headlights.
At Ron and Cranky's advice, I went over every connection and cleaned and reconnected my main ground lug (needed it) along with all other grounds. I did have one mistake in my headlight hi/lo beam connection which I corrected. All dash wiring, gauges, switches, etc is by the book. Damn thing is that while the headlight switch doesn't seem to be getting quite as hot as before, the friggin fuel gauge still moves up towards full when I turn on the lights. If I disconnect the ground at the sending unit it makes no difference. If I disconnect the signal wire, then it remains unresponsive. Any ideas?
