Measure how many ohms the solenoid on the columbia control has, find a ballast resistor that has the same ohms ---use that ---the columbia solenoids are not designed to have power to them all the time --just momentary while the clutch is down,
The first generation mopar electronic ignition has a dual ballast resistor ---one or both of them can be used ---series for more ohms ---I have used these to fake out lamp modules when led lightsare retrofitted
