Does anyone have a copy of the schematic for the MPFI GM computer? (like the one used on late 80's/early 90's J/L/N/F bodies) Not the pinout/wire color, but an actual component part diagram.
It would look something like this, only much more complex.

I think that is in my helm manual...not sure how many pages it would be. Its for a W body though.

Even for a W body the circut diagrams should be the same. Same computer right? Anything helps.
