Bridge the electrical compatibility gap between your towing vehicle and trailer with this highly practical PVC mini adapter plug. This compact, space-saving adapter is engineered for situations where the towing vehicle is equipped with a modern 13-pin (13P) outlet socket, but the trailer, horsebox, caravan, or utility hauler utilizes a traditional 7-pin (7P) connection system. The mini adapter delivers a seamless electrical transition, guaranteeing the correct and synchronized operation of all standard signaling lamps, including running, brake, and turn indicators. Molded from premium-grade, industry-standard, and weatherproof PVC compound, this device features tight moisture seals to shield internal terminals from dust and water ingress. Thanks to its ultra-compact design profile, it seats securely inside the socket without adding bulk, allowing a quick, tool-free installation directly out of the box.
