I need to order an engine wiring harness for my 1974 Challenger and it seems there are two different ones one until oct.73 and one after oct.73 does anyone know what the difference is ? I am not going to need the wires for the electronic ignition unit as i am going to use an HEI distributor but I will need the electronic voltage regulator wiring . It was a 318 car but now has a 71 440 .
