Hayes 81770 Endeavor® Brake Controller

The Endeavor functions on its ability to sense deceleration of the tow vehicle during braking. An internal sensor measures the amount of deceleration and sends a proportional amount of power to the trailer brakes. It comes with our exclusive Quik-Connect feature that speeds installation. The initial turn-on voltage and maximum output are adjustable to provide superior trailer brake responsiveness. The digital display indicates the amount of power being sent to the trailer brakes and can be adjusted to display in three modes (percent of power, voltage, or current). For 2, 4, 6 and 8 electric/hydraulic brakes. Lifetime warranty.
