In order to install a 7-way trailer wiring harness on the back of a trailer you'll simply need the Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness part # PK11898. The wires will splice into the tail light circuits that are already run to the rear. If you need to extend any of the circuits like the brake output or battery charge line you can simply purchase the correct gauge wire by the foot such as part # 10-1-1. We do offer the bonded 7-wire as part # DW04914-1 but this would be much too expensive to run the entire length of the trailer.
