ECM Pin Connection Diagram

Hello, I was wondering if anyone would happen to know where I would find a ECM Pin Connection Diagram for a Chevy Lumina APV (1996)? Any information would be greatly appreciated. Thanks in advance.

You'll have to get a copy of the GM service manuals. The diagrams are all in the back of the 2nd book called "electrical diagnosis". Look for the chapter called harness connector diagrams. It'll cost you about $95 for the set of two books, but I use mine all the time and wouldn't be without them.

Try to go to this link:

Check the HAYNES manuals for Lumina sedan which should be similar, Also try the Lumina APV manual, unfortunately it only goes to 1995. My 1996 Pontiac Trans Sport has a different PCM than whats shown for the 1995 minivans; its wiring is closer to the '96 3.4 L Lumina sedan engine. Chilton made a manual for the APV,etc covering past 1996 but I haven't been able to find one( out of print).
