Ballast resistor or re-use old coil wire?
I rewired my 1967 mustang with a new harness from Painless and the instructions say to connect the wire between the ignition switch and coil to a "ballast resistor". I checked some older threads and see that the original wire from the ignition to coil was a resistor wire that added an ohm or two of resistance, but there was no ballast resistor in the original design. I assume since Painless refers to it that the wire furnished with their harness is not a resistor wire.
My question is does some parts supplier sell such a resistor? I don't see one in NPD or Cal Mustang. Do I need to salvage my old harness to get the old wire? What will happen if I connect the coil direct from the ignition?
