If the diagram posted does not work, go by the local GM dealer and ask a Tech if they will print one off for you. I bought a GM service manual for my 1981 Blazer since I was redoing a lot of the original wiring and it was the best source for schematics. Alot of the diagrams like the one posted come out of the Haynes books aren't correct a lot of the time.
