Brand X Voltage PWM Controller For Internally Regulated PCM Controlled 05+ GM Vehicles

This is a voltage knob made for PCM controlled 05+ GM vehicles with the small rectangular 2 pin plug. It makes it plug and play with the GM 2 pin harness. There is no splicing of your stock plug required.

These are generally in stock and ship within a couple of days of purchase. 

They work on up to 4 alternators of the same type, if you’re looking for an alternative to wiring externally regulated setups for newer vehicles this is the option for you! 

There is no return policy on this item, you need to make sure you’re ordering the correct controller for your vehicle, message us for information if you are unsure!!!

This does NOT work on any other vehicle, and is made to work on PCM controlled vehicles only. 05-2024 GM 2 pin plug vehicles. The maximum voltage is 15.5v on brand x and OEM installed regulators. Some brands have a max of less if they use a lesser quality Chinese aftermarket regulator.

installation is relatively straight forward. Red wire on the knob will go to ignition. Black wire to ground. Plug this into the alternator.

there are no cancellations or returns on custom ordered items. We assemble these in house specifically for your vehicle.
