Will this work?

What they are showing here is "ignition 2" is hot during start, and goes back to the key, providing coil voltage during cranking. You basically will follow this diagram, except:

Pull the coil/ distributor / ballast resistor off the diagram, and jumper IGN1 and IGN2 together---if these are present on your key switch. That point, the point that used to feed the ballast, will now feed the small red wire of the MSD The big black MSD gets a good ground, an the big red goes through a fuse to live 12V

IT IS IMPORTANT not to connect anything to the coil except the two MSD wires. Do not connect a tach, nor a radio supression cap to the coil with an MSD

The only real difference in the MSD diagram you posted is that you will eliminate the Pertronix connections shown, and connect your Mopar dist to the connector "not used." It is important to get that correct,------reversing the wires will change timing and cause "rotor phasing" problems

What is not shown here is a starter relay which you will want to add if you do not have one, because of the solenoid current
