The "definitive" wiring diagrams (copies of GM's) can be purchased from NCRS for $15: http://www.ncrs.org/store/shop.cgi/p...75194161.11597 (you'll have to scroll a ways down the page). They also sell the AIM for $23 ($19 if you're a member).

Mr. VCuomo
There is no polite way to say this: but you don’t know what you are writing about. Definitive is an inaccurate term to describe any of the GM published 1956-1977 wiring diagrams whether they appear in a GM assembly manuals or GM shop manuals. Factually those GM illustrations were drawn long before any particular model year Corvette was actually manufactured. When the actual modsels were built differently, the wiring diagrams were NEVER corrected to portray the actual wiring. Some are close. None are accurate. None.
If you compare real Corvette wiring harnesses to the GM illustrations you will would find between 5-10 errors and omissions in EVERY model year. I have examined every one of these harness and do not rely on smoke and mirrors or cyberbabble to make these conclusions.
1977 in particular has one of the most inaccurate GM wiring schematic published because there were essentially two different wiring harness produced for every harness system when the alarm changed from the fender switch to the door lock switch. They are vastly different, and neither is represented authentically in any GM publication. Truthfully there are no accurate 1977 schematics in publication – anywhere.

PS Colored in ebabe versions are merely colored in inaccurate copies of the GM black and white publications. The AIM is an excellent reference manual, but only when you are able to determine and recognize the errors presented.

Mr. Coenen: If GM published it, it is "definitive" even if it is inaccurate.
And, BTW, there is indeed a "polite" way to say what you wanted to say. Just delete the first sentence - that would have been polite. As I'm Batman says, the dripping sarcasm is wholly unnecessary.
And I am (and after this, maybe "was") one of your customers.
