QWORK® 3M 7 Pin Trailer Light Board Extension Cable Spiral Male to Female Adapter for Car Caravan Truck

7-pin trailer extension cable for the electrical connection between the vehicle and the trailer or caravan, with 12 V power supply, to transmit a light electronic signal from the car/vehicle to the trailer. The spiral harness has a cutting length of 3 meters and a working length of 2.5 meters, which provides the extra length needed for tight turns with trailers. Coiled cable stays off the floor to prevent fraying on dirty terrain. Polyurethane (TPU) outer sheath not only prevents oxidation and corrosion, but also maintains elasticity and flexibility even at low temperatures. Pure copper plugs and tinned terminals ensure excellent conductivity, with a nylon shell around the connector. The socket also features a rubber dust cover that protects against dust and moisture. WIDE APPLICATIONS - The coiled extension cable with trailer adapter is compatible with most European RVs, RVs, tractors, trailers, cars, trucks and semi-trailers.
