I have a rock buggy that the previous owner put a 1995 impala ss motor in it. He did a hack job on the wiring and I'm currently in the process of rewiring it. My question is there are 2 wires in a plug on the back of the alternator. I think they are brown. Will the alternator charge without these 2 wires hooked up. And if not where do I wire them to. I've searched and searched and not found much.
