Ignition Coil

The ignition coil is oil filled and the wire terminals are designed so that interchange with other types of coils is not possible. The "DEC" terminal (Green wire) connects to the ECM. The "BAT" terminal (Red wire) connects to the ignition switch, ballast resistor and the control module.
