If YOU could provide a photo would be much easier.
You have a diagram?
Your harness should have a big thick black wire with an eyelet end..........goes to the alternator output stud.
There should be another wire, usually green, with a push on connector goes onto the alternator field..........that's it..........two wires
Now knowing what you HAVE for an alternator..............
If you have a 70/ 80's Mopar, it will have one more field connection (push on connector) Just ground that
But not knowing..............what..........you........have..........because........I..........don't........have........RUSTY WHERE IS THAT CRYSTAL BALL!!!????
