The stock Pontiac ignition has a resistance wire that is a cloth covered stainless steel wire that goes to the coil. This drops the voltage down so the points don't get cooked. Points don't like 12V. There is also a wire that comes off the starter solonoid to the coil so while the engine is cranking and the electrical system voltage drops, the coil gets a boost of voltage. I've got an Accel super coil and points so there is a ballast resistor in addition to the resistance wire. If you are running pointless ignition, usually you run 12V straight to the coil. If you go to the Accel website, I seem to remember that they had info on setting up ignitions.
