Description
xOverview
Upgrade your trailer wiring with the Adullama 4-Way Trailer Wiring Harness. This 5-foot jacketed cable delivers a robust, four-pin connection that aligns with standard 4-way flat trailer plugs. The combination of sturdy conductors and a weather-ready jacket ensures a reliable link between your vehicle and trailer without the guesswork of makeshift fixes.
Durable, weather-ready construction
Built with 16 AWG pure copper wire and a reinforced PVC jacket, this harness resists wear, exposure to the elements, and abrasion. The result is a cable that remains pliable yet tough in changing conditions, ready for daily loading, unloading, and occasional off-road use.
