77 wiring diagram
Anybody got the wiring diagram for the 77. I am willing to buy one but want to see whats out there. I am working on labeling the wire harness under the dash tonight. Also whats the difference between the 77 early and 77 late and how do I tell the difference. Thanks

Early 77's have the keyed alarm in the left front fender. Late 77's have the alarm integrated with the drivers door lock and there is no key in the left front fender.
There is a large format (roughly 11" x 17") book out which specifically shows each circuit run in the 77 Corvette. Try ebay or some of the Corvette parts vendors (Corvette Central or Ecklers).

Get in touch with Don Olson. Great 22x34" laminated diagrams printed in color to match wire colors.

Doc Rebuild also has good diagrams, as they show the connectors at the ends of the wires. http://www.docrebuild.com/
