Ok, so the grey harness red wire, does it power a latching relay in the controller? As I know I don't have power there all the time. I assume it sees the priming pulse to latch the relay in to provide power to the controller through the molex connector?

Ive tested the positive connection at the injector and I don't have a constant 12v at pre crank position, as I would expect, that's why I ask if it's a latching relay.
