Ok, here's my delima. I'm trying to figure out exactly what voltage or signal the wire on an alternator from a 96'-97' Isuzu Rodeo is expecting, to go to the PCM or Powertrain Control Module. Older vehicles do not have this connection going to the alternator. Anyone know what exactly the PCM is doing? Is it the connection that turns the regulator on and off on the alternator? If so, anyone know what voltage or resistance is expected on it? I can expound more and even include some wiring diagrams to shed some light on this if needs be.

3.2L V6 SOHC 1996 Isuzu Rodeo. Flowmaster exhaust / K&N High Flow Intake / Kenwood headunit / Audiobahn Subs / Alphasonik/Kenwood/Sony Amps / 180 amp High-output alternator / Redtop Optima battery / Custom hood w/ scoop
