I'm hooking up my Aquamist meoh/water injection and it runs on injector duty cycle, so I need to tap the signal and ground wire for the #1 injector. I'd prefer to do it at the pcm, so does anyone have a chart or location guide to the pin-outs for the PCM in a 2000 f-body?

I'd hate to have to undo all of the wiring harnesses to trace it back.

Ok, thanks to this link:

I know that it's #36 on the blue harness for the signal wire, but what about the second wire coming off the injector harness, does that go back to a common ground?

I don't think it would matter, but I'm just not sure.

The injectors have a common power. The ground gets switched.

Ok, so the signal wire is the actual ground, and then I just need to tap a positive source. Thanks.
