Anayguto 6 ft Pure Copper 7-Pin Trailer Wiring Harness + Waterproof Junction Box

Overview

Introducing the Anayguto 6 ft Pure Copper 7-Pin Trailer Wiring Harness with a Waterproof 7-Way Junction Box. Built for heavy-duty towing, this setup combines a robust copper-core cable with a weather-ready junction box, designed to keep signals clear and connections steady as you move from site to site.

The core of the system uses solid copper conductors for stable signal transmission, paired with a durable ABS housing that resists rain, road spray, and dust. Four open and four closed grommets emphasize a well-sealed profile, helping protect electrical paths from the elements and ensuring reliable performance across a range of weather conditions.

Materials, Durability, and Weather-Ready Design

The 7-wire harness is engineered with pure copper conductors and a heavy-duty plug, all housed in a rugged ABS enclosure. The sealing strategy includes multiple grommets to form a protective barrier against moisture and dust, making it suitable for outdoor use and rugged work environments.
