* With points type ignitions, does the black wire from the distributor connect to the NEG side of the coil?

* On applications using a 2 prong ballast resistor, can a 4 prong resistor be substituted if a 2 prong is not available? I'm wondering if one spade from each side would work.
I rarely have worked on points type cars, only the factory electronics or a converted car.
Thank you.
