The voltage regulator controls the amount of circulating voltage. Proper wiring is required for the regulator to perform as required.
The wiring harness from a typical alternator has three wires. One is for grounding, one is from the battery, and the other is from the voltage regulator. In a GM alternator however, there may be two wires or only one wire. It depends on whether you have an external voltage regulator or not, and if the alternator simply grounds itself to the bracket it's attached to. The best way to find out is to trace the wires to their sources.
Remove the fuel regulator retaining screws. Remove the fuel regulator wiring harness. Reverse the process to install the new fuel regulator.
The regulator can be found on the top of the alternator. Remove the wiring harness from the regulator. Remove the retaining screws from the regulator. Reverse the process to install the new regulator.
I know for the 6 wire wiring harness that goes to the voltage regulator white=Battery, red=ignition, yellow=charge, but Im not sure what green, blue, or the white one that has a black strip. Im also trying to figure out what these mean.
It is located inside the inner primary at the front of the motor below where the voltage regulator is mounted. The voltage regulator will have a wiring harness that plugs into the stator plug on the outside of the inner primary (the stator is located under the plug). You must remove the outer primary and the clutch basket to access the stator.
A voltage regulator is just as it says. It regulates the voltage that the alternator in your vehicle puts out. Too much voltage and you'll overamp your wiring, and too little can cause parts not to function properly.

The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.
On fuel injected models, the Engine Control Module regulates voltage. On carbureted models the voltage regulator should be mounted on the firewall near the ignition coil. It should look like a small metal box about the size of a pack of cigarettes and be held on by two small bolts and have a small wiring harness (two or maybe three wires).
On fuel injected models, the voltage regulator is not in the alternator, it is, unfortunately, part of the computer. The field winding in the alternator receives it excitation voltage from the computer. The computer monitors the system voltage and provides what it thinks is the appropriate field drive to keep the battery charged. The bad part about this is that you have to replace the whole engine computer if the regulator portion of it fails (at least $200.00 or more) I know this from personal experience. It might be possible to install an external regulator or install an alternator with built in regulator but you will have to modify the wiring.

You need to buy an adapter harness. Do not cut into your wiring harness.
