Electric Brake Control Wiring

Note: US Dept. of Transportation requires that trailers equipped with brakes have a trailer break away system for activation of the trailer brakes, in the event that the trailer should become detached from the tow vehicle during highway travel. Trailers equipped with electric brakes typically use an emergency breakaway battery kit such as the TAP Brakemaster kit. The battery for this system MUST be able to maintain brake activation for 15 minutes minimum. The break away system normally contains a battery trickle charger for battery maintenence.
