everything that i'm finding deals with Camaro and Vette alternators.

my plug is labeled P L I S. what wires do I need to run to get this thing working?

What alternator are you using???

What wiring harness and operating system are you using???

Since the different systems use different plugs we would need to know what your using, but I found this on tech for you. Maybe it will help?

I believe GMT 800 Silverado's from

99-00 use terminal L
01-04 use terminals L and F.
05-07 Classic used Terminal F

I also found this S I L P connector view. http://i127.photobucket.com/albums/p...ese/cs130d.jpg

Hope this helps some.

I figured it out. no wiring harness, or operating system. i'm building a carbed ls2 this time around. I just ran one of the pins to a keyed 5v source. bingo.

this helps:


I just wish it said what the L and I terminals are for. I only hooked up the L pin to a 5v source. I left I alone. hopefully I don't burn anything.

Are there any local Alt/starter rebuild shops that could tell you what each wire does ?

In the Diagram it shows the warning light hooked up to L.

the light is there to drop 12v down to 5v I believe. I had a 5v source so I skipped out on the light. a resister can also be used to drop the voltage.

Pink/Black might be your field duty cycle signal from a regulator, unless the alt has one built in. I don't remember the difference between 2 pin vs. 4 pin alts.



This is the 01-04 connector.
