In addition to universal wiring, we also stock a wide range of vehicle specific kits.
12N (7 pin): This black socket is fitted as standard when installing a towbar. Its function is to work the trailer road lights.
12S: This supplementary (grey) socket is added to the 12N (black) socket for towing a caravan. The main function is to maintain the fridge temperature while driving and provide a small trickle charge to the battery.
13 pin: The new Euro wiring is equivalent to the older 12N and 12S options. Mainly found on 2009 onwards caravans, the 13 pin will not only work the road lights but will also maintain the fridge temperature while driving and power ATC (13 pin trailers will a reverse light).
