Info on FBO ecu unit

If an HEI module, you shouldn't need the ballast resistor, and better with an e-core coil. Do they suggest that? If upgrading an earlier engine with points ignition, why would anyone change to the Mopar ECU wiring, unless using the actual Mopar ECU? That would be clumsy wiring to the 5-pin connector and none of the ballast resistors would be needed. For HEI, easier and cheaper to use the GM 8-pin module (1985-95), GM coil, and cable which connects them. TrailBeast here used to sell a kit, or grab parts cheap at the junkyard. I use it on my 1960's Mopars.
