Here is a link to the site I got the wiring diagram from:

I used a junkyard aternator for a mid 80's chevy capriece.
I Wired the #2 terminal on the GM Alernator to the Batt Post on the alternator. Hook the wire that goes between the Generator lite and the stock regulater to the #1 terminal on the alternator. All the other wires for the stock charging system are not used. I removed these wires from the harness to clean things up. But, it should not hurt anything to just leave them where they are.
