The only versions I can find are very hard to read. Does anyone happen to have a better copy of say an '88 or '89?

Normally I'd just take the Y-body pinout and call it good, but (and I'll check if I can after work) it appears there is a wire already in the oil temperature location (C13 off the top of my head) which I don't think was used in any application BUT the Y-body. This ECM was already pulled from a car, but has 1989 3.1 Grand Prix on the tag. Was purchased from a wrecking yard, and they are small enough I think they labeled it correctly.

I know it's highly unlikely at best that all 1227727 pinouts were not the same, and the possibility exists that I read the connector numbers wrong. But the wire color in what I think is the same location doesn't match the Y-body, and enough other wire colors are different that I would like to verify what I'm looking at with the proper manual.
