melsg5 is correct, the reason for running a new wire is that the Points ignition system runs on just 9.5 Volts (12 Volts when starting that is why there is a wire that runs to the coils from the starter) the used a resistance wire to decrease the voltage for the points system. Your HEI will not run properly unless you have a full 12 volts running to it. Good luck with the conversion, well worth it if done properly.
