Prodigy® P2 Proportional Brake Controller for Trailers with 1-4 Axles, Grey Manufactured by: Tekonsha

The Prodigy P2 electric brake controller supplies power to your tow vehicle's brakes proportionally. This means that your trailer brakes at the same time and with the same strength as your vehicle - even in reverse gear. If you have to slam on your truck's brakes, the trailer's brakes respond instantly, too - there's no delay. Therefore, your vehicle's brakes aren't overworked from trying to stop the entire load, and they suffer less wear and tear compared to time-based controls. The P2 also cuts power to the trailer's brakes when your vehicle is stopped - extending the life of the magnets and brake shoes in the trailer's brake assemblies.

Aside from smoother, more efficient braking, the Prodigy P2 also has a boost feature that gives you more initial braking power for towing heavier loads. The boost setting sends 13 or 25 percent more power (depending on which setting you choose) back to the trailer brakes, thus compensating for heavier loads. The boost feature gets more power to the trailer brakes exactly when you need it most, and your fully loaded rig brakes smoothly and comfortably.

This brake controller levels automatically as you drive, so there's no problem using it on steep hills or when towing through the mountains. The self-leveling feature also makes the Prodigy easy to install: Simply mount it in your cab at any vertical angle (it has 360-degree rotation). The P2's continuous diagnostic check monitors your connection and magnet condition, so you can fix any problems before they lead to issues on the road. The power-save mode reduces battery drain when the controller isn't in use.
