Bypassing ballast resistor

Look at the two connectors. One pair are already jumpered together. This is the end that provides power from the switch. The other connector has two wires. You only need to jumper from EITHER termialof the two power connector to whichever wire in the remaining one goes to the coil. Just look at the colors or check continuity

The 4th wire "went" to the ECU and likely was not used, anyhow, unless you have an original old "5 pin" box

The old coil wire goes now, to the "small red" of the MSD

The big black are ground and the large RED "full time" battery such as starter relay. Good idea to put a breaker, fuse in that line

I cannot tell for certain in your photo, I think this connector is power and if you look at that is already jumpered. Just unplug either end of your new jumper (leave one end in the connector) and connect the free end to what you identified as the old coil + wire in the opposite connector

Am I old? I adapted my first Mopar breakerless ignition into my 70 340 swapped RR in about 1973
