IGN-6 Six-Tower Coil Pack

The IGN-6 ‘wasted spark’ style coil pack at a glance could be mistaken for a stock Chrysler ignition coil, perhaps off of a Dodge Intrepid, but it’s not. Though it appears to be molded from the same tooling used to make stock replacement coils for some Mopar products, and would bolt right up to many LH platform cars and minivans — inside, you’ll find a much hotter winding. This coil pack can deliver up to 58 mJ per spark if you have a hot enough ignition module to drive it. Use with HEI type plug wire boots.

This coil also has a handy set of plug wire numbers stamped on it. These numbers are correct for a 1-2-3-4-5-6 or 1-6-5-4-3-2 firing order (many V6s; this coil was originally designed as an upgrade for Buick V6s). If you have an engine with a different firing order, such as most inline sixes (or different cylinder numbering), you will have to change the wires to match. For example, if you have a 1-5-3-6-2-4 order (most inline sixes), you’d pair the wires 1-6, 5-2, 3-4.

Here is the connector pinout, viewing the connector from the top, looking down at the pins. Connect “B+” to switched 12 volt power; do not feed it voltage with the key off.
