      Complete Engine Wiring. The Engine Wiring Harness, 350ci, w/Automatic Trans is designed to connect and integrate the electrical components essential for the operation of a 350 cubic inch small block engine with an automatic transmission. This harness streamlines the wiring process, ensuring proper function of engine sensors, ignition, transmission controls, and starter interlock systems. Its use is critical for maintaining factory-correct electrical operations and supporting vehicle safety features.

      Materials and Build. Constructed with durable automotive-grade wiring and protective insulation, the harness is engineered for longevity and resistance to heat and vibration. The connectors and terminals are designed to fit precisely with factory components, providing reliable conductivity and secure attachment points, all finished with a protective coating to resist corrosion and wear.

      Installation. Installation requires familiarity with vehicle wiring schematics but does not typically involve drilling or permanent modifications. Proper routing and connector mating ensure a clean and functional setup tailored to the specified engine and transmission configuration.

      Application. This harness is specifically made for the 1974 Corvette C3 equipped with a small block engine and automatic transmission, including integration for the seat belt interlock system as originally equipped for this model year.
