wiring up Proform Mopar HEI Distributor # 440-434

I bought the Proform Mopar HEI Distributor # 440-434 what I'm not sure about is how to wire it up
1st do I leave the ballast resistor or bypass it I'm thinking bypass it?
2nd the stock ignition box (this is a 1971 Plymouth with a 360) do I keep the box plugged onto the system or unplug it and find the start and run wires and plug them into the distributor or do I need a specific wiring harness for this to work?.
