An important aspect of towbar fitting is the wiring which is required to power either your trailer lights or caravan internal electrics. This is often overlooked when booking a towbar or can be difficult to understand exactly what your vehicle requires if you have none or very little knowledge.
Basic wiring to the sockets and plugs is a rather straightforward procedure, however when you require audible replays and bypass kits to cope with the complicated cars of today, this is when things can start to get tricky. Luckily for you, we do this day in day out. We are fully conversant with all aspects of towbar wiring and are stockists of ECS, Brink, Westfalia, Witter electric kits who are market leaders in the field of towing and trailer electrics. All towbar electrics we supply have a great reputation for quality and durability.

Single 7 pin electrics, also known as 12N towing electrics are needed to power the lighting on a trailer, caravan, cycle carrier or anything you're towing. (The single 7 pin electrics power left and right indicator and taillights, fog lights and brake lights.)
If you don't require any further power to your towing counterpart, the single 7 pin electrics socket will be your main choice.
Twin electrics is a 2 plug system which combines the single 7 pin 12N electrics socket with a 12S electrics socket. You will need twin electrics if you require more power than what a single 7 pin socket can provide on a pre 2008 manufactured UK caravan (post 2008 UK caravans are fitted with 13 pin connectors). The twin electrics will power everything that a single electrics system powers plus reversing lamp, battery, power supply and fridge. The brown pin 5 in most cases is not used when wiring tow bar electrics and it is important to ensure that the white pin 3 cable is earthed.. In some cases a split charge relay might be needed in order for the power to switch divide from charging a leisure battery and the car battery.

13 pin towing electrics are the most modern style of towing socket, all EU caravans post 2008 will be fitted as standard with a 13 pin electrics connector. This is essentially a 2-in-1 socket, it has all the capabilities as twin electrics in one rather than 2 separate sockets. 13 pin towing are more adaptable for detachable tow bars that have a spring mounted single socket plate that can be folded up behind the bumper so that it's invisible.
Conversion leads are available for 13 pin towing electrics to twin 7 pin towing electrics or twin 7 pin to 13 pin towing electrics if your vehicle has a 13 pin socket and your caravan has twin 7 pin towing plugs or vice versa.
