So after some research I've got a 1998 Camaro Alternator and harness. I'm now using a 2001 Camaro PCM. Below is the diagram I used to wire it in. The Alternator "L" terminal is going to the PCM "Alternator Turn On" pin. The Alternator "Field" is getting switched power, and the 3rd Alternator Terminal is getting Battery+. Do I even need the switched power to the field on the 98 camaro alternator? Everything I see has just the L terminal hooked up. Also, from the PCM "Alternator Turn On" pin, will I need a light or resistor on that line? Here's the diagram I used:

Cool

All you need is the L terminal connected to pin 15 of the red pcm connector.

If you are running a 99-02 OS the field terminal is not monitored or controlled by the pcm file. They primarily used the F terminal on trucks.
