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.
