Electronic Control Module

There are 6 wires leading from the control module, 2 to one connector and 4 to another. The White and Red wires are for the ignition feed circuits. The Dark Green wire turns the power to the ignition coil on and off. The Light Green wire supplies a compensated ignition spark timing signal to the electronic control module from the Micro Computer Unit (MCU). The Black wire supplies the distributor ground circuit. The sixth wire is not used.
