Ignition Coils

Three twin tower ignition coils are individually mounted on the ICM. The system uses a waste spark method of distribution, where each coil fires two spark plugs simultaneously. Each coil is serviced separately.

Two terminals connect each coil pack to the ICM. The 20A F/P-IGN relay center fuse provides a fused ignition feed to each coil. The other terminal at each coil is individually connected to the ICM. The ICM completes and interrupts the primary circuit ground path to each coil at the proper time, which energizes each coil one at a time.
