  • Retractable wiring harness reel
    Patent number: 7264478
    Abstract: A retractable wiring harness device attaches to the trailer frame near the trailer hitch and contains a length of retractable wiring harness which extends from a housing member to install within the wiring connection on a towing vehicle, the trailer wiring harness wired into the lighting and braking wiring harness of the trailer. When the trailer is disconnected from the towing vehicle and the retractable wiring harness is disconnected from the wiring connection of the vehicle, the wire cable is withdrawn into the housing member to retain the retractable wiring harness, keeping it off the ground and out of the way of the trailer hitch.
