Gentlemen:
I am researching the likelihood of using a GM HEI amplifier on another vehicle. Can any of you provide me with either info on what is taking place at each of the four pins of a GM HEI amplifier, or a site where I could find such info?

So far, all I have been able to learn from searching here is that the resistance of a correctly functioning GM pick-up coil is on the order of approx. 500 ohms, but that's about it. Specifically, I need to know which of the pins goes to 12V, which goes to the ignition coil, and which two go to the pick-up coil. I believe I can figure out which two go to the pick-up coil. I'm making the assumption that on one side, one terminal will go to +12V, the other to the ignition coil, and the remaining two on the opposite side go to the pick-up coil.

I have a vehicle that uses this system, but it's easier and cleaner to ask here than crawl into the truck and start disassembling one of the few things that works well on that truck.

Thanx in advance,
