Ignition Module Question

mcnoople said
The 5th pin isn't for the tach. Tach goes to neg terminal on dizzy. I forget what 5th pin is but i think it was for 4 pin ballast resistors. I haven't seen a 5 pin module in years and never saw one from a aftermarket source.

5 pin modules draw power from the 5 ohm side on a 4 wire resistor and it goes to pin 3 of the ECU, can run any car with or without them
