GM 4-Pin HEI Electronic Ignition Control Module Wiring Connections/Diagram with a Magnetic Pickup Coil

This electronic ignition system operates with full 12 volts. It is recommended only for ordinary lawn & garden equipment. In order for the engine to accelerate at full RPM, the magnetic pickup coil requires a high-output/performance 4-pin GM HEI module, 1.0 ohm ignition coil, metal core spark plug wire and a copper core spark plug gapped at .025". IMPORTANT: The coil and/or module may burn up if the ignition switch is left on for more than 5 minutes with the engine not running. (The module does NOT have a built-in timing retard.)
