I've only been able to find the R/V diagrams for 1991.
The closest I've found for the C/K are 1988 but a bit of comparing to the harness I have shows there's plenty of differences at the bulkhead connector. For example, the VSS wires are in different locations in 91 than they were in 88.
Then there's all the "fun" stuff of the wires that went to the ECM, by way of the bulkhead connector and instrument panel instead of right through the ECM harness bulkhead grommet.
Since the 82 GMC doesn't have antilock brakes I'm attempting to figure out what wires are for it so they can be removed. Already pulled out the AC clutch wire.
I copied the bulkhead connector diagram from a 1980 diagram then pasted it into an image with a list of the circuit/terminal numbers from the list at the start of the book. I want to do the same for 1991 C/K TBI 350 + 700R4.
