I'm gonna check the leads off the Alt, but I could also use the fuel pump relay I think. Are there any negative aspects to tapping power off that relay? I would only run the tap right to a 30A relay so its not like there would be any extra draw on the circuit.

I got this wiring diagram... It seems I should be able to tap the signal coming from the ECM. Any thoughts?
