Am I wrong in thinking I'm off one pin? The white wire has 12v key on ..

Never mind this is correct, pin 76 is for the injector.

I've seen 2 different pin out schematics, one says 75 is not used and another says it need 12v key on??? I don't think this has anything to do with my problem. I think either the pcm is bad or I have a crossed wire in my harness..
