Original 1978 Chevrolet Dealer Electrical Wiring Diagram Service Manual. This very informative Factory Manual covers Corvette [including Limited Edition] Models. These detailed Wiring Diagrams are what the Dealership used to diagnose and repair your Corvette. Very useful and rare since they were not offered to the public. Manual shows some wear, blemishing and soiling from being damp but the information is all there and it will serve its purpose [see photos]. It is creased down the middle from being folded. ST-361-78
