HEI conversion help

Hey TrailBeast, I'm trying to do this same thing in my 73 Duster. I would like to delete some of the older wiring as well. Did you keep the "voltage regulator" that runs to the alternator, or did you delete that as well? I just assume not keep the ballast "jumped" wiring if I dont need it. I have a GM E-coil with both pig tails, and a 4 point ECU for my set up.

Regulator and all wiring for it stays as is.
Remove or bypass any ballast resistor.
Connect your new coil + to the two (both) wires Ignition 1 and Ignition 2 that used to go to your ballast.

Once that's done you can clip all the wires from the Mopar ECU all the way back to the harness, then wrap the taped off ends back into the harness.

When done you can move on with mounting and connecting the new module and distributor reluctor wires.

This might help if you don't have it.
