The Hopkins 47105 is a 4-flat trailer wiring extension connector that adds 32 inches of extra reach to your towing setup. This extension connector provides the extra length needed when your vehicle’s wiring harness doesn’t reach your trailer’s connector, eliminating the need to strain wires or create unsafe improvised connections.
Designed for both DIY enthusiasts and experienced tower operators, this connector makes trailer hookup faster and more reliable. The included components—dust cover, cable ties, dielectric grease, ground screw, and pre-terminated ring terminal—give you everything needed for a complete installation. The ABS plastic housing resists impact and weathering, while corrosion-resistant terminals maintain reliable connections in wet or harsh outdoor conditions.
