Since the early 2000’s, automotive technology moved rapidly forward in introducing network systems in vehicles which allowed the detection of a trailer. In many cases, not only did the manufacturer design the vehicle to detect the trailer, but created enhanced features within the network, which actually makes it vitally important for the trailer to be ‘seen’ and not ‘hidden’ from the towing vehicle. The advantages of a dedicated wiring kit are that the vehicle will know when you are towing and will automatically adjust the following if the vehicle has them:
- Brake Electronics
- Engine Electronics
- Cruise Control or A.C.C.
- Parking Aids
- Reversing Cameras
- Lane Change Assisting
- Suspension System
- Engine Cooling System
Vehicle specific wiring kits in the majority of cases connect directly into the manufacturers dedicated socket. Some vehicles also need a compulsory download from the vehicle main agent to make the vehicle aware that these towing electrics are fitted, which is included as part of our service using the latest software.
7 pin plug/socket for trailer towing pre 2013
Single electrics or 12N electrics are used for towing trailers and for use with cycle carriers
12S electrics commonly referred to as the twin electrics socket and has a grey cover are used in conjunction with the 12N socket when towing caravans, trailer tents and alike. The 12S electrics are used to charge the leisure battery, the charge for this is taken from the towing vehicle charging system via an automatic split charging relay so that both leisure battery and vehicle battery have sufficient power. The 12S socket also contains a power feed for the reversing lights on the caravan.
13 Pin Trailer / Caravan
13 pin Euro towing sockets are the newest style of towing socket and as of September 2008 all caravans manufactured will be wired up with 13 pin plugs that meet ISO11446 ( international standards organisation ) and the U.K. representative B.S.I. ( British standards institute ) requirements. The 13 pin socket is also more adaptable for detachable tow-bars that have a spring mounting single socket plate that can be folded up behind the bumper so that it is invisible.
