MSD & Ballast Resistor Question

WIRE FUNCTIONS
These are the two heavy gauge wires (12 gauge) and are
responsible for getting direct battery voltage to the Ignition. The
ignition has an internal fuse so no fuse is necessary.
This wire connects directly to the battery positive (+) terminal or to
a positive battery junction or the positive side of the starter solenoid.
Note:
Never connect the alternator.
This wire connects to a good ground, either at the battery negative
(-) terminal or to the engine.

Connects to a switched 12 volt source. Such as the ignition key or switch.I stoped hear because MSD do not tell you to connect the switched wire to the Ballast Resistor .This switched wire needs 12 volts.The wire that comes from the +switch to the Ballast Resistor go,s to the red small wire at the MSD box.Not after the Ballast Resistor.Why reinvent the wheel.

I think this is where some guys get mixed up. They think just because they have the 12 gauge wires hook directly to 12 volts they forget to bypass the ballast for the switch wire which also needs a minimum 12 volts, it will work but can cause false symptoms when it doesn't get a full 12 volts.
