I just picked up a 2006 LS4/Auto drive line. I am having a hard time finding a "pin out list" for the E40 PCM used with this computer. The computer I have, has a C! "BLK" connector with no wire in pin one and a Gray wire in pin 2. C2, the blue connector has a TAN/BLK wire in both pin 1 and pin 2. C3 the gray connector has no wire in pin 1 and a BRN wire in pin 2. all the lists I can find do not have the same wires in the same pins. any help in finding a pin out that corresponds to the connectors I have would be great.

You can download the factory service manual here and it will have the pinouts.
