AL‑KO ATC Wiring Looms
AL‑KO ATC (Automatic Trailer Control) is an electronic stability system fitted to many modern caravans. It monitors caravan movement and applies the brakes automatically if instability or snaking is detected. The wiring loom connects the ATC control unit to the caravan’s electrical and braking circuits, ensuring the system can operate as intended. Using the correct loom helps maintain reliable ATC performance and proper communication with the tow vehicle.
At Mallorr Caravan Services, we supply genuine and compatible AL‑KO ATC wiring looms suitable for a wide range of UK caravan models.
