The unit is rated for up to 4.2 amps for Turns/Stops circuits and 7.5 amps for the Taillight circuit. Draws power directly from the vehicle battery and uses less than 5mA of the vehicle circuit for sensing to turn the trailer functions on and off. Will work with either LED/Incandescent bulbs (vehicle & trailer). Has integrated re-settable Short Circuit and Overload protection, to safeguard itself and the tow vehicle from shorts and installation wiring mishaps. Designed not to send feedback thru the vehicle circuits. The trailer brakes will override the hazard lamps when the brake is activated. The taillight circuit has been upgraded to work with vehicles that use a pulse width modulation (PWM), this will allow the converter to turn on fully and gives the trailer lights full brightness during activation. Will work with most vehicles that have a multiplex system for lighting. Will not work with vehicles with low-side switch. Can be used on a 2 wire or 3 wire system. All solid-state components in potted encapsulation. Includes integrated protective cover.
