If you have noticed that the wiring harnesses on your C3 Corvette have become brittle, dry or scorched, it is time to replace them immediately. Corvette Mods is proud to offer this replacement 1977-1978 Corvette Engine/Starter Extension Wiring Harness (with A/C).
The plastic used for the original wiring harnesses was too porous and allowed harmful, corrosive elements (oxygen, moisture, air pollutants, etc.) to pass through completely destroying the wires in your C3 Corvette. Common results were electrical shorts, malfunctioning gauges and even potential catastrophic loss.
Our new harnesses are manufactured in the United States using only the best wiring components to ensure long lasting function and peace of mind. The terminals have been dip soldered to limit the resistance voltage loss making this harness a must have for your C3 Corvette. All of the engine/starter extension wiring harnesses have been fully tested and approved.
