Correct ballast resistor

The key is to compare the resistance specs of your new coil with the oem mopar coil. If they are the same, you are ok. If your new coil is a little higher, you are still probably ok.

If your new coil is lower resistance, then you will need a larger value ballast to keep the current through the ecu the same.

Mixing ignition components is not the best idea unless you have some verification that they will work together.
