Trailer Wiring Harness with 4-Pin Flat Male Plug, 12-Inch 16-Gauge Color-Coded Leads and Rubber Housing – CURT 58030

A trailer wiring harness provides a four-way electrical connection for tail lights, brake lights, turn signals and ground. The trailer-side CURT 58030 uses an industry-standard four-pin flat male plug with 12 inches of bonded, color-coded 16-gauge wire ready to splice into compatible existing trailer wiring.

Top and bottom grip tabs make the molded black rubber connector easier to insert and remove, while the rust- and corrosion-resistant housing suits road exposure. The plug is designed for compatible two-wire vehicle systems and standard four-way flat sockets. The selected configuration contains one harness, and a separate two-pack is listed; installation requires correct wire identification and secure weather-resistant splices.
