Introducing the new Hayes G2 trailer brake controller with an audible signal alert for connection continuity€”a market-exclusive feature that makes for safer braking. The easy-to-find, easy-to-use manual emergency braking control lets you apply full power in emergency stopping situations. The three-axis accelerometer technology automatically levels and senses the rate of deceleration. The G2's large, high-resolution diagnostic liquid crystal panel is recessed to eliminate glare. This easy-to-read digital display indicates the amount of power being sent to the trailer brakes and allows adjustment in three modes (percent of power, voltage, and current). This advanced controller has a "power boost feature" which gives you the ability to apply more inital braking power when towing heavier trailers. The G2€”with its sleek, low-profile design€”is compatible with the new Hayes Universal Quik-Receiver mounting sleeve to make installation a snap. For 2, 4, 6, and 8 electric brakes. Limited lifetime warranty.
