Ballast resistor-> 4 prong to 2 prong

Any ballast resistor is only necessary for a non-12v coil, IMO. I've ran a 12v coil with any mopar ignition box without a resistor for years. Had a shitty msd coil leak on me once but other than that, it'll handle it. Dammit I hate msd. What an overpriced, trash ignition system.
