MSD Questions

OK, I know there have been a few people to ask questions about hooking up their MSD box.

I have the orange and black wires running to the coil. The white wire is to run to the old (-) wire for the coin, now the small red is suppose to run to switched power, is this the old (+) coil wire (according to the diagram)?

The ballast resistor, can I leave this off the car or do I need to run with it?

Any help is appreciated.
