Otherwise the coil will have a short life.Īll connections to be made with 14 gauge wire, and please do use di-electric grease when you crimp or snap on a spade connector / butt connector / bullet connector… the environment under the hood will foul up and rust the connections if you don't. You can use a 4 pin box with a 4 pin resistor, but you cannot use a 5 pin box with a 2 pin resistor.ĭan Stern also pointed out that you will need a standalone, late-model, spool-type coil, either GM or Mopar, or an MSD Blaster, which fits the stock can-type coil bracket. They do the exact same thing the 4 pin simply as extra ballast integrated into it.
