Old fashioned reverse engineering.

Maybe you should request information as an ecm remanufacturer?  There are a few rebuilders, they must have obtained information in some way.

They may not release schematics at all.  GM is a provider of rebuilt ecm's.  They have no need to support the business of repairing and rebuilding computers.

I know that it's easier to pull a hen's teeth than obtain Delco service information for audio products, even those which are 15 years old.  And once you get service info, finding parts is even tougher.
