I'll poke around some wiring diagrams tomorrow at work. The two smaller wires should be an exiter wire and another wire for the idiot light/gauge but I'll confirm that tomorrow. Could make a house call if need be. I tend to end up in some wiring nightmares at work:I have three wires from the original alternator harness that need to go somewhere. I have a heavy gauge white with blue stripe wire, and two smaller wires that plugged into the back of the original alternator, white with a blue stripe and white with a black stripe. I am using the stock alternator that came on the 1998 Chevy 4.3.
I have searched around on here, reviewed wiring diagrams, and looked at other sites, but haven't found a clear answer on how to run the original wires so everything functions as it should. Would hate to turn the key and nothing on the truck works, other than the motor since it is stand alone, or it goes up in smoke from an electrical fire. Any pointers are appreciated or if you want to stop by and check things out, cold beer is waiting.
