This NEW SUN converter provides an inline adapter with color-coded leads and a sealed housing to convert three- or multi-wire trailer outputs into a two-way flat configuration. Built with full copper conductors and a long 80-inch cable, it simplifies hookups for utility trailers, small boats, lawn equipment trailers, and other towed gear while resisting corrosion from road and weather exposure.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the converter preserve signal reliability on the road?\u003c\/h3\u003e\n\u003cp\u003eThe harness uses 100% copper conductors to maintain low resistance and consistent current for brake, turn, and tail signals.
