Electronic Control Module

Each Duraspark II module has 6 wires (a 2-wire connector and a 4-wire connector). See Figure. The Red and White wires are the ignition feed wires. White wire is for cranking mode, Red wire for run mode. The Red wire circuit contains a 1.1 ohm wire resistor.

The current in the primary circuit of the ignition coil is turned off and on by the Green wire. The Orange and Purple wires transmit signals to the module from the armature and pick-up coil in the distributor. The Black wire is used to ground the distributor. The module is powered whenever the ignition switch is in the "RUN" or "START" position.
