How do you hook up the wires to a starter on a 1978 350 rocket?

The large one from the positive side of the battery attaches to the large post mounted on the starter solenoid and a smaller purple wire that attaches to the small post on the starter solenoid marked "S". The small post on the starter solenoid marked "R" is not used with that vehicle. Any accessory power wires would also attach to the large post on the starter solenoid.
