I think ballast resistors aren't necessary for a 6V system, but I might be mistaken. I have a Napa 6V coil in my 31 and it runs fine, no problems.
Assuming you have a positive ground car, the negative side of the coil (power) should connect to the ignition switch, and the positive side of the coil should connect to the distributor.
This is correct. Positive ground tends to shunt the norms sometimes. Fact, most coils don't care about voltage. Old GM cars had 2 wires in the harness before it got to the coil for low voltage run, high voltage start. Of course the Mopars we know and love had the ballast resistor but also 2 wires for 12V start, ballast run. Use that as you will, but it may have been wired backward and would really overheat the small windings rather quickly. Good luck, let us know.
