Default LT1 Alternator help

Putting a LT1 in a Nova. Can any one tell me if all I need is the one wire or the three wire plug for the Alternator? Does it need a inline resistor wire? The Alternator is a CS144 140 amp.Thanks for your help.

Lt1 alt from factory is 2 wire. The main battery wire and a smaller wire that goes to the charge light but is very important to have as it provides the exciter current to the voltage regulator, without which the alt won't charge. The wire has a 470 ohm resistor in the circuit. The exciter wire goes to terminal L of alt. Terminals S & F are not used

So if I put a 470 ohm resistor to a 12 switched power source I should be good? I'm useing a aftermarket gauge system insted of the factory idiot light. Thanks for your comments.
