This NEW SUN harness solves that by converting wiring quickly while protecting conductors from moisture and corrosion. Built with full-size copper conductors and a sealed junction, the cable gives you a long reach and dependable electrical performance for trailers, RVs, boats, and utility carts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this converter make mismatched plugs work together?\u003c\/h3\u003e\n\n\u003cp\u003eThe converter routes the trailer's brake, turn and tail circuits into a 4-pin flat output so older or differently wired tow vehicles can power trailer lights correctly.
