You can still get original GM wiring diagrams on evilbay for a pretty reasonable price.

There are PDF files in the library

Just chucked up and bought a factory manual with the separate wire diags for my issues with mine. After looking through the ads I found a good deal on both from a seller on EBAY. Made copies of the wiring diagrams so I can mark up....buy factory manuals for most of my stuff - most times they know their stuff !

Hey guys, Im about install the cluster from CLASSIC INSTRUMENTS - I need to HACK my wire harness and tie it into the new cluster - I've been looking for a wire diagram. There are so many - and I'm not very good at reading those. Im trying.....But it's freaking hard. I don't have 'that' ability like other do.

Anyone know of a wire diagram that's straight forward? that tells me exactly which wire is which? something for DUMMIES...

I just received a colored, laminated wiring diagram for my 1981 from ClassicCarWiring.com, it is way cool.
