Correct Voltage regulator for 100amp Single wire Alt?

The voltage regulator is built in. Do not wire a wire alternator through your factory VR.

What is a self exciting (one-wire)alternator? How to solve Alternator Wiring Problems
Self-Exciting Alternator makes no need for Alternator Wiring Diagram
The Self-Exciting alternator is an alternator that has a special voltage regulator that doesn't need an ignition wire to activate it.This is usually based on a chevy alternator type and only requires a battery wire connected to the battery terminal. The voltageregulator which controls alternator output contains circuitry that uses the residual magnetism in the alternators rotor fields to determine when to turn the alternator on and off, a standard Delco alternator would not do this without an ignition activation wire.The regulator does this by sensing the RPM the alternator is turning, when it gets to a certain rpm the voltage regulator "turns on". Typically you start the vehicle, rev the motor slightly with the si series and alternator starts charging. With the CS series delco alternator with the self exciting voltage regulator you do not need to rev the engine.
