WIRING THE TOWBAR

Description:
7-pin heavy duty connectors used on trailers, caravans etc. to connect the obligatory lighting (12N) and
auxiliary power systems (12S) to the towing vehicle. Both connectors are similar in appearance apart
from the gender of the pins, designed to ensure the connectors cannot be connected to the wrong socket.
Typical Applications:Trailers, Caravans etc.
- 12N connector used to connect obligatory road lights.Caravans
- 12S connector used to charge caravan battery, power fridge and equipment etc.
Pin Assignments:
The above diagram shows the numbering and gender of the pins from the back of the plug (the side the
wires are connected to). The numbering would be the same viewing the socket from the front but the contact
gender would be reversed.

12N connectors are normally coloured black. Pins 2, 5 and 7 in the plug are female, others are male.
12S connectors are normally coloured white. Pins 2 and 5 in the plug are female, others are male.
Note that the 12N and 12S ground wiring must not be connected together and must be connected to the
towing vehicle separately via the associated connector.
* 12S pinouts to post 1999 European standard. Pre-1999 caravans are wired differently, check a specialist
caravanners website for details of this and more in-depth discussion of 12S caravan wiring.
Connector Assembly Instructions:
Normally screw connectors. Thread the nut and glad onto the cable before wiring up the plug and fully
tighten gland after assembly to provide strain relief and water resistance. Be especially careful to ensure
there are no loose strands of wire as a short circuit whilst towing could cause a breakdown of the towing
vehicle or lighting.

THE TOWBAR

EC Type Approval Standards

Witter are at the forefront of testing to the EC specification requirements using computer controlled servo-hydraulic test rigs which put towbars through a punishing two million cycle fatigue test.

The requirements became mandatory under European Law from the 1st January 1998 and were implemented in the UK on the 1st August 1998. This means only towbars Type Approved to 94/20 EC can be fitted to any light passenger vehicles first registered on or after 1st August 1998. Our commitment to these regulations has been ongoing for a number of years. In 1995 we were awarded the first UK towbar Type Approval number 00-0001. All new towbars for light passenger vehicles are designed, tested and certified to 94/20 EC. For further information on Type Approval please see our link to our Questions and Answers.

European Directive 94/20 EC also specifies the dimensions, locations and clearance of the 50mm towball. The centre of the towball should be between 350mm and 420mm above the ground when the vehicle is laden.

BS EN ISO 9001
As further proof of our commitment to quality, Witter have full accreditation as a BS EN ISO 9001 Quality Assured Company. This internationally recognised quality standard helps to ensure that our towbars continue the tradition of excellence established over 50 years ago.

EC Type Approval Q and A

Questions & Answers as applied in the UK
Q. Why was European Type Approval for towbars introduced?
A. Directive 94/20/EC was introduced as part of European Whole Vehicle Type Approval to provide a common standard throughout the European Community, thus creating an open market. Irrespective of where a towbar has been manufactured, providing it has been Type Approved, a customer will know that it has been manufactured to a known technical and quality standard.

Q. What may happen if I don't fit a Type Approved towbar?
A. If your car is first registered on or after the 1st August 1998, you could be prosecuted for an infringement of Construction & Use Regulations or your Insurers may decline to pay out in the event of an accident claim. If you are unsure which towbar to fit contact your local Witter specialist, who can be found under National Stockists.

Q. I only tow a small trailer on rare occasions, surely I don't need a type approved towbar?
A. YES. The towbar must be certified even if not used for towing! Otherwise it does not comply with the Road Traffic Act.

Q. Can I transfer a non approved towbar from my 1996 Vauxhall Vectra to the new Vectra I am getting, which is registered after August 1998, if I fit it myself?
A. NO. Only Type Approved towbars can be fitted to vehicles that are registered on or after the 1st August 1998.

Q. Does 94/20/EC mean that I can only have a swan neck towbar fitted as supplied by the vehicle manufacturers?
A. NO. A towbar with the popular two - hole flange ball faceplate and towball made by an Independent towbar manufacturer can be EC Type Approved. Witter already have a range of over 250 covering the vast majority of vehicle applications.

Q. I have a Ford KA and want to tow my small trailer but nobody lists a towbar. Can I have one specially manufactured?
A. NO. When EC Type Approving the vehicle, the manufacturer did not declare that it was suitable for towing. It therefore has no specified towing capacity and no specified mounting points. Towing with, or even the fitment of a towbar to any such vehicle registered on or after the 1st August 1998 would make you liable to prosecution.

Q. How can I find out if my new car or model variant, is EC Type Approved for towing?
A. For a new car or model variant a definitive answer could be obtained by examining the vehicle VIN (Vehicle Identification Number) plate, which should have four figures stamped into the lower edge denoting its carrying capacity.
VIN No. (known as chassis number)
XXXX kg -(Max vehicle weight)
XXXX kg -(Max train weight i.e. vehicle and trailer)
1. XXXX kg -(Max front axle load)
2. XXXX kg -(Max rear axle load)
If no train weight is specified then the vehicle is not approved for towing, and therefore cannot legally do so. If a train weight is specified then the towing weight is this figure less the maximum vehicle weight The VIN plate is usually located under the bonnet. However it can sometimes be elsewhere.

Q. Can I fit a Type Approved towbar myself or do I have to go to an authorised fitter?
A. YES. You can fit the towbar yourself provided that it is installed in accordance with the instructions provided, but you may prefer a Witter specialist to carry out the complete installation to include the often awkward towing electrics.

Q. How can I tell if a towbar is EC Type Approved?
A. It will have a label, data plate or stamping showing an E No. (e.g. E11*0001*00). This figure denotes that it is EC Approved in the UK (E11), has approval number (0001), of EC Document revision 0. In fact this is a Witter type approval for the Ssangyong Musso the first EC Approved UK towbar!

Q. I am going to buy a used 'S' registered Mondeo. The towbar fitted is not Type Approved. What do I do.
A. Insist that the towbar is immediately removed and replaced with one that is Type Approved. If you meet any resistance report the matter to your local Trading Standards Office.

Q. I have a non EC Type Approved towbar on my 'P' registered BMW 320 (an EC Type Approved vehicle, registered in the UK in January 1997). Can I legally use the car to tow my caravan to Germany?
A. YES. Although the EC Regulations are applied differently and introduced at different times in different countries, it is the country of registration that defines how and when you comply with the relevant EC Regulations.

Q. If I have an accident whilst towing on the Continent using a non EC Approved Towbar will I be liable to prosecution for not having an EC Approved towbar?
A. NO. Provided the vehicle is registered in the UK before the 1st August 1998. However, if the towbar is considered to have contributed to causing the accident for reasons of inadequacy e.g. a poor quality 'home made' unit, or obviously incorrectly installed, then naturally prosecution may be a possibility. Always fit a good quality product.

Q. My local motor dealer says that my warranty will be invalidated unless I fit the manufacturer's towbar.
A. 94/20/EC was designed to create free trade. If you fit a Witter Type Approved towbar it will not invalidate the vehicle warranty. Under EC Block Exemption Rules a motor vehicle manufacturer cannot prevent a franchised outlet from supplying or fitting components deemed to be of equal quality to that supplied by the vehicle manufacture - such as a Type Approved towbar.

Q. Can I fit a 'drop plate' to an EC Type Approved towbar?
A. Only if the towbar has been submitted and tested for EC Type Approval using a 'drop plate'. Some Witter towbars for 4WD off road vehicles have been tested in this way, e.g. Range Rover, Land Rover Discovery and Defender, the new Mitsubishi Shogun and Mercedes M Class. Your local Witter specialist will be pleased to advise you.

Q. Can I fit a cycle carrier or stabiliser between the towbar faceplate and the towball, when the towbar is EC Type Approved?
A. YES. Witter towbars are tested with a minimum spacer of 25mm between the towball and the towbar.

Q. Must the towball have a separate EC Type Approval and have a Type Approval number?
A. No. All Witter towbars have a specified towball part number which has been tested and approved as a component of the towbar. These have their own identification Z11. The identification is clearly stamped on the top flat section of the towball, set inside an outline of the Witter logo.
