Samramra 50 Ft 7-Way Trailer Wire Harness Kit

Upgrade your towing setup with the Samramra 50 Feet 7-Way Trailer Wire Harness Kit, engineered for reliable performance across a wide range of utility and recreational vehicles. Designed for standard 12V trailer systems, this heavy-duty assembly utilizes high-quality 14-gauge stranded Copper Clad Aluminum (CCA) conductors to ensure efficient and dependable power delivery for essential electrical functions.

Built to withstand demanding road conditions, the harness is enclosed in a robust black flexible PVC outer jacket that effectively resists oil, moisture, and abrasion. This rugged exterior is engineered to maintain flexibility in extreme climates, performing reliably from scorching summer heat down to -15°C. Inside, a specialized protective cloth layer encases the color-coded insulation, facilitating clean wire stripping without messy powders during installation.

Featuring seven distinct SAE-standard color-coded wires—black, brown, blue, red, green, yellow, and white—this kit simplifies the connection process for tail lights, electric brakes, turn signals, and reverse functions. Whether you are performing a professional installation or a do-it-yourself replacement on an RV, camper, horse trailer, food truck, or utility trailer, this comprehensive wiring solution delivers the durability and precision required for safe towing.
