Please help I'm in the process of replacing the 13 pin socket on the towbar. I have a Kuga attached to the caravan. When I tested the Kuga's fog lights go off when caravan fog lights on. I therefore bought a replacement 13 pin socket with fog off (Hela). Except when I came to remove old socket it looked a standard socket with no mechanical fog off switch. Is the Kuga cambus system handling the fog light on/off? I'm concerned that putting on the new socket with built in fog off switch will interfere with the Kuga system. Anyone got any ideas or solution. Thanks
