Electronic Control Module

Each Dura-Spark II module has 6 wires (a 2-wire and a 4-wire connector). See Figure and Figure. The Red and White wires are the ignition feed wires. The White wire is for cranking, and the Red wire is for operation after the engine is running.

The Red wire circuit contains a 1.1 ohm resistance wire. The current to the primary circuit of the ignition coil is turned off and on through the Green wire.

The Orange and Purple wires transmit signals to the electronic control module from the reluctor (armature) and pick-up coil (stator) in the distributor.

The Black wire is used to ground the electronic control module through the distributor housing.
