I am trying to finish a 73 Duster that I bought . The car was a 6 cylinder car that someone started to convert to a V8 car . It was minus the distributor. I am putting a new HEI in it with a hot coil but can't figure out how to hook it up. I finally got a set of instructions but don't know what I need to do with the ballast resistor or the ECM. Do I hopk them up or bypass. May just go back to standard distributor rather than this hipo set up. BTW the motor is supposedly a performance built motor. Help!!
