The Voyager brake controller incorporates patented braking sensor by Tekonsha and is the best value you will find for smooth and secure trailer braking. Its compact size and features, like a bi-colored LED brake monitor (to assure a complete connection to trailer brakes and give an indication of relative braking power being applied) make the Voyager extremely versatile. Voyager minimizes interference with tow vehicle electrical systems, uses a four wire hook up, has a broad setting range and is compatible with most any vehicle.
