3M 7 Pin trailer extension Coiled Cable, 12V Core cable Towing Adaptor with Male to Female for Caravan, Truck, Car Spiral Spring Cord, plug, light board

WEATHER-RESISTANT CONSTRUCTION: Built with a TPU outer sheath combined with pure copper pins and tin-plated terminals, this extension lead withstands exposure to rain, dust, and road moisture. The waterproof housing protects the internal wiring and prevents corrosion, making the cable suitable for all-season towing in outdoor environments 3M SPIRAL STRETCH DESIGN: The high-elasticity coiled cable stretches from its compact resting state to a full 3 metres when in use. This spiral spring structure lifts the wiring off the ground during transit, reducing the risk of the cable dragging on the road surface or catching on obstacles underneath the vehicle during sharp turns and manoeuvres. PLUG-AND-PLAY OPERATIO: No tools, cutting, or rewiring is required for installation. Simply connect the 7-pin plug into the vehicle’s towing socket and attach the 7-pin socket to the trailer, caravan, or light board. The pre-wired 7-core lead instantly transmits 12V lighting signals including brake lights, indicators, tail lights, fog lights, and reversing lamps. EUROPEAN STANDARD COMPATIBILITY: Designed to work with European standard 7-pin (12N) towing electrics, this extension cable connects to most caravans, trucks, motorhomes, tractors, and commercial trailers. It establishes a secure connection between the towing vehicle and the trailer for synchronised lighting operation. HIGH-QUALITY CONDUCTIVE MATERIALS: The internal pure copper pins provide stable electrical conductivity for consistent lighting signal transmission, while the tin-plated terminals offer additional resistance against oxidisation. These materials ensure the extension lead maintains reliable performance over repeated connections and disconnections.
