How to Install the Spark Control Module in a Corvette
The Chevrolet Corvette has incorporated a ignition module, which is also referred to as a spark control module, since the late 1960s. The ignition control modules control the spark of the ignition coil and proper sequence of firing. A failed ignition module will not permit a car to start; failures can occur due to damage, heat or moisture. Ignition modules and their installation vary based on year; consult a manual specific to your year for more detailed information.
