Pertronix III set up

I wouldn't cut any factory wires. Every old Mopar I got had been similarly hacked up by gomers, always the steering column connector because they didn't know how easy it is to release the terminals.

You can buy (rare) short spade-spade connectors which let you connect the females together. Otherwise, just make a short male-male jumper wires, using Packard 56 terminals. Easiest is to just connect all 4 together. Note that 2 are already jumpered together (blue +12 V IGN source), so you only need jumper 3 together. The reason you have 2 ballasts is that one restricts the supply to the Mopar ECU. The other restricts the coil supply. You don't need either restriction with a later HEI ignition (GM or Pertronix Ignitor II or III). Note, the original Pertronix Ignitor does require the coil ballast.
In the end I did not cut any other wires besides the two that were going to the ballast coming from the ignition box which would not get used. Otherwise I just open the harness and pulled the two that go to the distributor connector oh, and the ones black and yellow that went to the coil negative and to the ignition box which would not be used. Which only leaves two wires left the brown and the blue which I believe are ignition run and ignition start which I assume are the wires I would be jumping together like I have shown in the picture I have them crimped for now but plan to solder Unless a jumper wire is different then I will have to do it that way.
