1978 Dash Wiring Harness 2nd Design
1978 Dash Wiring Harness 2nd Design with timer on right side of Glove Box.
Our Original Design Series™ wiring harnesses are manufactured exactly as the wiring was made when your vehicle left the factory in St. Louis. These harnesses are made to the exact O.E.M. (original equipment manufacturer) specifications, using the original factory blueprints, and are factory-correct in every way. These are full-assembled, ready to install, “plug & play” accurate reproduction wiring harnesses. You will NOT have to cut any wires, crimp any terminals, or make any modifications to these harnesses when installing them in your 1977 Corvette.
