Alright, I got new gauges, the 2.5” from dcc, and im trying to wire them in. the diagram I'm looking at shows that the positive end gOes in to the brown white Connecter, did that, but then it shows the - going in to a green connecter, well I can't seem to find it. I think its supposed to attach to one coming from the headlight, but a green brown comes out of that and the other cable goes to the side of the headlight. Am I missing something here or do I need to wire in some kind of ground?
