ECU diagram access

So, im looking at the ECU diagram in the FSM right now, but i cant figure out how to find what i want. all i seem to be able to get to is the view of the connector with the pin numbers on it, but i need to find injector 1 and some other stuff, anybody got any info for me? there has to be a list somewhere on what all the pins are, but i cant seem to find it

Terminal # 1 (R/B wire) is your Injector #1.

See if this helps:

thanks. ive more or less figured out how to get the pins. i figured there was a better way, im just looking through the DTC's for a related circuit and following back to the ECU.

Are you looking for a complete list of all pins and what they do?

Trouble Diagnosis - General Description: ECM Terminals and Reference Value.

Starts on EC-139 for the '02, EC-149 for the '00, and right around those pages for all A33s.
