Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
