Alternator Wiring

[Chevelle LT1]

If anyone can help out it would be greatly appreciated.

Right now, I am trying to wire up the alternator, and I'm not sure which wires go where. The engine is a 1994 LT1, the alternator is out of a mid-90's Vette, and the wiring harness is Painless. The painless kit calls for one wire to go from the alternator to the battery (Got that done), but the other wire has to be plugged in as an exciter to the internal voltage regulator. Well, I went and bought a GM plug for the alternator, but it has more wires than I was expecting (letters on the plug are P-L-F-S, read left to right). If you look at the attached pic, clearly the large diameter wire goes to the battery, but does anyone know which of the other wires to use for the exciter?

I've attached the photo of the harness for reference. Thanks to all who can help!!

Scroll about 3/4 of the way to the bottom and they tell you what each of the letters are and where they need to go based on the type of wiring you have.

Your alternator doesnt look the same as the one shown here, but plug sounds like it is the same.

You rock! That was what I needed...

I recommend running the "S" terminal to a central junction port rather than back to the battery lug. I realize it looks cleaner that way but the "S" terminal is the remote sense line and you will have a low voltage condition at some accessories if not done properly. I run mine to the 50AMP circuit breaker on the fire wall that feeds the dash and lighting circuits.

Thanks for the info, I'll keep that in mind when I finally get time to wire it up.
