Question: Getting the most out of a stock looking ignition system.
There was a member here (and I've considered doing so) who took a 4 pin HEI and shoehorned it into a factory Mopar ECU box, empty box
Wiring a 4 pin ECU is simple, 4 wires and ground
My emergency system, an hei and a coil
Ground, battery, coil wire, and plug into the Mopar distributor
Diagram. There's a plastic locator pin you must break off the bottom of the ECU or else drill a clearance hole. Mount the ECU to a good ground, flat, sheet metal or a heat sink with thermal grease, ground to one of the screws, and hook up as shown. Important to hook the distributor connector as shown. Even with a factory coil, this system gives a hotter spark than the old Mopar ECU
