This trailer 4-way flat connector can splice into your pre-existing trailer wiring and connect to your vehicle to power your brake and turn lights. The 4 flat output connects to your trailer's tail lights, brake lights, and turn signals. Constructed with strong molded rubber adaptor plug and bonded wires, this connector plug is a sturdy replacement for your trailer, as well as color-coded with 12 inches of wire to make installation easy. The 4 flat connector is common on many trailers that do not have braked axle, including smaller boat trailers and utility trailers.
