This is an aftermarket controller for the GM NPP valves found on newer vehicles. This device allows a user to add NPP mufflers (with the GM actuators) to a car that isn't equipped to control them. Want to put Chevy SS NPP mufflers on your G8? No problem!
This device is simple to hook up and only requires ignition power, ground, and a switch to toggle the trigger wire to ground. It features the correct connectors to plug right into the GM actuators
A switch is not provided. Some wiring is required.
