Corvette wiring diagrams are fully laminated (both sides) and are BIG for easy viewing. (approx. 18" X 22" for the 1953-74 diagrams and approx. 21" X 24" for the 1975-82 diagrams). These are complete schematics of each base model car (cars with no options). They are highly recommended for anyone who is doing their own wiring. If you accidentally smear grease or oil on these diagrams while working on your car, no problem. They easily wipe clean. Printed with permission from General Motors Corporation.
