Of course its not the dimmer switch. That's makes no sense.

Glad that person's description clicked with you. Different peaople have different ways of learning, or respond better to different explanations.

Sorry above was the best I could do.

You don’t think it could be the dimmer switch then? My actual headlight switch is new as well. But this black wire was hanging beside it. Not sure if it should be pushed into the harness or pushed onto the tab on the switch. I’m also wondering if the wires are in the right positions within the harness
