HEI in Mopar ECU casing

Ground at the module is important too. The module pulls the coil - to ground too charge coil. It also needs trigger signal from pickup coil. The pickup connectors can be troublesome.

Turned out the pick up coil gap needed to be tightened up. Starts right up now. I would love to know how the heck the gap just mysteriously widened while it was sitting in the garage. It was fine last time i drove it..
