What is the purpose of the wire between the positive of the coil to the "R" of the starter solenoid? ???

During normal operation, the coil gets 7-8 volts through the cloth-covered resistance wire that feeds it from the ignition switch, which improves point life. During cranking while starting, the wire from the "R" terminal on the solenoid to the (+) coil terminal feeds a full 12 volts from the solenoid to the coil, bypassing the resistance wire, providing more voltage to the coil for starting. When the engine starts and the solenoid disengages, the coil (+) is again fed by the resistance wire.

Thank you for the response John.I just bought "the Breakerless conversion system" from Rick's.And in the Instruction it is mention

this ignition is designed to work with a ballast resistor.

There is no ceramic resistance or anything else to add since the resistance is part of that white wire.
Is that correct?

Yes, that's correct - the cloth-covered white wire has the resistance required; previous to 1967, a separate ceramic-encased ballast resistor was used.
