Converts vehicle functions from a 3 wire system to a trailer 2 wire system. Draws power directly from the vehicle battery and only uses less then 5 milliamps of the vehicle circuit for sensing (standby current < 2mA) to turn the trailer functions on and off. Heavy duty! Rated for up to 4.2 amps for turns/stop circuits and 7.5 amps for the tail light circuit. Has integrated re-settable short circuit and overload protection, to safeguard itself and the tow vehicle from shorts and installation wiring mishaps. All-solid state components in potted encapsulation. Works with either LED or incandescent bulbs (input/output) this gives trailer lights full brightness. Designed not to send feedback thru the vehicle circuits. Interprets/decodes multiplex signal inputs (BMW & Mercedes applications).
