      Description

      Transmission Control Spark System. The Throttle Control Switch Jumper Wiring Harness provides a critical connection between the engine harness and the transmission controlled spark (T.C.S.) switch. It helps regulate ignition timing by disabling vacuum advance in specific gear ranges to reduce emissions, enhancing engine performance and compliance with emission standards.

      Construction and Appearance. This wiring harness is built with durable, high-quality materials designed to withstand engine compartment conditions. It features protected wiring with reliable connectors engineered for a secure fit, ensuring consistent electrical performance in demanding environments.

      Installation. Installation is straightforward and requires no drilling. The harness is designed to connect directly between existing engine harness connections and the T.C.S. switch, simplifying replacement or upgrade procedures.

      Application. Specifically designed to fit Chevrolet Corvette models from 1971 through 1974, focusing on the C3 generation where the transmission controlled spark system was originally equipped.
