The new alternator is a one wire setup from my Trans am, but I have an exciter plug that has the 3 wire setup from my 5.3's alternator. I know that one of the wires gives a 12V signal to the alternator to start charging, but I don't know which one it is.

I think I need some pinouts and then I could fix it up.

Anyone have the pinouts for an 02 LS1 harness? I have the one for my 5.3L...

Thanks again.
