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.
