Towbar Options

There’s 2 styles of towbar available.  A flangeball towbar, where the towbar has a faceplate with the towball bolted to it.  Or a swan neck towbar which has a one piece neck with the towball attached.

Either option can be available as detachable, this is where the neck can be removed when the towbar is not in use. If you’re not sure about the style of towbar that you need please take a read below

The design of a Flange Ball Towbar

Flangeball Towbars

On a flange towbar, the bar has a faceplate which the towball and electrical connections are mounted. You can also get a Swan neck which is a one piece and nicer looking finish.

Swan Neck Towbars

Rather than a plate to mount the tow ball onto, this is a one piece that is mounted further back on the bar leaving the vehicle with a much cleaner look.

Detachable Towbars

Both flangeball and swan neck towbar styles are available in a detachable option for most models. With a detachable towbar you can remove the neck when the towbar is not in use leaving the vehicle looking like it does not have one.

Towbar Electric Sockets

Towbar electric sockets come in three types. The socket you require depends on your intended use for the towbar.  You will require either 7 pin, twin 7 pin, or 13 pin electrics. Our team are more than happy to advise however, we have set out the 3 different sockets below for your information.

Single 7 Pin, 12(N)

7 PIN 12(N) Electrical Socket

Single 7 Pin Electrics are the ‘standard’ towing electric plug.

You need this fitting if you will be towing a standard UK trailer or using a standard cycle carrier on which you need to power a reverse light.

7 Pin electrics are also used for UK caravans manufactured prior to 2008.

Twin 7 Pin, 12(S)

7 Pin 12(S) Electrical Socket

Twin Electrics are used when you will be towing a caravan manufactured prior to 2008.

The grey 12(S) supplementary socket is fitted in addition to the Single 7 Pin socket to provide power to charge the caravan battery.  This will also provide power to the interior functions of the caravan.

This type of socket has been replaced on caravans built after 2008 in the UK. New caravans now use the 13 pin standard socket.

13 Pin

A 13 Pin Towbar Socket

13 Pin Electrics have been standard in most other European countries for some time.

This is replacing the 2 separate socket currently used in the UK. The 13 pin socket is essentially the two 7 pin sockets merged in to one.

All caravans manufactured in the UK from 2008 are fitted with an ISO 13 pin connector as standard. This system uses one socket with 13 pins inside, instead of the traditional two separate 7 pin sockets.

Towbar wiring types

You will also need to decide how you would like the wiring to be installed on your car. There are two ways that towbar wiring can be installed.

It can be installed using either universal aftermarket wiring, using what is known as vehicle specific or dedicated wiring.

Vehicle Specific wiring can be a lot more expensive, but has many benefits to justify the cost. When getting quotes for a towbar installation it’s important to understand what you’re looking for. The ‘cheapest’ way to install the wiring is rarely the best.

On older cars you have the option to decide how you would like the wiring to be installed, you can choose between universal aftermarket wiring, or vehicle specific wiring depending on your budget.

On newer cars which have safety features built in, the car would only be fitted with vehicle specific wiring.  Wiring is fitted as standard so this will be included in the price that you are quoted.  In the future all cars will require this type of wiring to be fitted.

Using universal aftermarket wiring on these cars would mean that essential safety features are not active when you are towing. 

To help you make an informed decision, we have detailed the difference between the 2 wiring options below.

Universal Towbar Wiring

Until the introduction of vehicle specific wiring kits, Universal towbar wiring kits were the standard method for the fitment of aftermarket towbar wiring.

This is a lower cost option than vehicle specific towbar wiring however, it does have some compromises as a result.

Universal towbar wiring provides all the lighting functions that are needed to keep you legal while towing your trailer or caravan.

Vehicle Specific Wiring

Vehicle Specific Wiring, sometimes known as ‘dedicated wiring looms’ or ‘plug in kits’, are becoming ever more popular for towbar wiring installation. To put it simply this is the way the job should be done.

Each kit is designed specifically for the vehicle that it is fitted to, and rather than soldering or using ‘Scotch Locks’ to connect the towbar wiring, which is the case with universal aftermarket wiring, these kits interface with the vehicle systems in the same way as the vehicle manufacturer intended.

Due to the complex nature of dedicated wiring it is inevitable that is more expensive than universal wiring.
