Not modified just designed after the first years of the Mopar electronic ignition where one side is the start circuit and the other side of the ballast is the run circuit. The later 2 prone ballast has only the run circuit.
Ah, no.
The four prong setup used one side for the coil just like the two prong setup. The other side was used with the 5 prong ECU and was the biasing resistor for the power transistor.
The four prong ECU's didn't require an external biasing resistor. So if you have a 4 prong ECU you do NOT have to use the 4 prong ballast resistor.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
