Our valve controller kits need a 12v source of power and a ground wired up to the control unit to operate. A third wire coming off of the control unit acts as the antenna. An included cable runs from the control unit to a solenoid to supply a signal. When the key fob is pressed, it sends a signal to the control unit, which determines if the solenoid is open or closed. The valve actuator / diaphragm will allow the valve to open or close depending on if there is a vacuum or not.
The SOUL valve controller fobs can also be paired with your factory garage door opener buttons, or HomeLink on your Porsche as well. Just follow the instructions to pair your car with device and hold down the desired key fob button to link functionality.
