Wiring Harness, 1970 Manual Tansmission Engine

Over time, your 1970 Corvette's Engine Wiring Harness degrades and begins to fall apart. Our complete engine harnesses for all 1970 with manual transmissions are a must have for your Corvette Restoration project.

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 1970 Corvette.
