Electronic Control Unit

There are 6 wires leading from the control unit, 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 electronic control module from the Micro Computer Unit (MCU), and the Black wire supplies the distributor ground circuit. The sixth wire is not used in this circuit.
