Grab the 1980 GM Wiring diagrams (foldout pages) and the 1981 GM service manual (the 1981 wiring diagrams are in the back on 8.5x11 pages but are harder for me to follow than the big foldouts)

The first few pages are a table of the GM circuit numbers with the corresponding colors and functions.
The bulkhead plug positions and other termination point pinouts are identified by GM Circuit Number in the big foldout pages.
