Ecu and ballast resistor questions


That distributor does not require any ballast or ECU.
The ECU and coil are a matched set and both are inside the distributor, and "ready to run" as is.
All it requires is power to it in the "Start" and "Run" positions both of the key, so you need to find those two wires, connect them together and power your distributor with them.
They both used to go to the ballast resistor, so finding them isn't hard using a test light and they should be right where the ballast used to be unless they were cut off by someone.
