Fueling & Injection - Need help with finding pin-out for #1 injector.

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.

Thanks.

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?

See if this helps.

It goes to a 15A switched power fuse.

Injectors on all cars receive an ignition based 12v supply. The each injector has a ground trigger to open/close the injector as required.

It is this wire you need for the controller.

Thanks for the replies guys. I got it figured out. Hopefully I'll have the system live in the next few days once things around here calm down.
