Proform Multi-Speed Fan Controller (PR67039)

PROFORM Brushless Fans have A LOT OF POWER. If you'd like to turn them down a little, then this simple controller is for you. Simply connect this controller to the Green wire of the PROFORM Brushless Fan, and hook up the 12 volt (+)(-), and you're good to go. Watch the video to see how it works.

Important Notes:

1. If you'd like to have this controller in the driver's compartment, you will need to extend the wires. 
2. The controller is not weather proof, so you will need to protect it if left under the hood.
