Ignition Coils

Three twin-tower ignition coils are individually mounted to the ignition control module. Each coil provides spark for 2 plugs simultaneously (waste spark distribution). Each coil is serviced separately. Two terminals connect each coil pack to the module. Each coil is provided a fused ignition feed. The other terminal at each coil is individually connected to the module, which energizes one coil at a time by completing and interrupting the primary circuit ground path to each coil at the proper time.
