Tools

The fitting of a towbar can be done by a competent person with a set of metric spanners, a metric socket set, a torque wrench, combination pliers, assorted screwdrivers, assorted hexagon keys, a basic multimeter, and a electric hand drill with bits.  However, some vehicles have special fittings for which the correct tool must be used.

Model Variations

We make every effort to accurately describe the models to which our towbars fit.  However, it should be noted that vehicle manufacturers may make changes to models after their initial launch which could prevent the towbar from fitting correctly.

Bumper Changes

The most common variation to the original specification is the rear bumper with changes to the fixings and the addition of spoilers or skirts.  Many of these variations will be fitted by the standard towbar but  some may require cutting of the bumper valance or skirt.  Take care not to mark the body with the bumper tips when removing and refitting the bumper.

Exhaust Changes

The size and position of rear exhaust silencers change frequently either when replaced with aftermarket products or due to factory design variations. When fitting the towbar care must be taken to ensure adequate clearance to the exhaust system which will expand and vibrate.  Careful movement of exhaust brackets, bending of support bars and checking of support rubbers usually overcome any potential rattle.

Number Plates

Some vehicle number plates are set below the British Standard recommendation.  The plate must be moved so that it is not obscured by the towing equipment and illuminated in its new position.

Drilling Holes

Check to see that all is clear on the far side of the hole before drilling the vehicle chassis.  Remove or protect carpet and trims and watch out for wiring looms, fuel tanks, and fuel pipes.  In many cases the towbar can be used as a guide. Take special care as the drill bit breaks through as it can be drawn through very quickly and may damage parts on the other side.  Treat all holes with a zinc rich paint or under seal to prevent rust formation.

Wiring Looms

Make sure that all wires are protected from sharp edges by using grommets and tie straps.  Any wiring that runs close to the exhaust must be protected with a heat shield.

Insulation

Sound insulation which is stuck to the steel at fixing points must be removed to allow washers and plates to seat properly.

Special Imports

Many of these vehicles have the same name or appear the same shape as the standard UK models but there are frequently important differences in the chassis and bumper design.  Usually mounting points are omitted.

Nuts and Bolts

When fitting a towing bracket the chassis and body must be inspected for corrosion or damage.  All suspect areas must be repaired before fitting and towing.  All bolts must be tightened to the correct torque setting as specified in the fitting instructions and checked regularly.

Wiring

All trailers used on public roads must be fitted with lights.  These will operate in conjunction with the vehicle lights by means of a 12N plug and socket arrangement.  The following is the standard seven core cable wiring code used in the United Kingdom.  Pin numbers relate to the pins in the plugs and sockets.

For 12N sockets with a integrated fog lamp cut-out switch, an additional pin is provided which can be used to disable the fog lamp when a trailer is connected.  The following is the standard eight core wiring code which is used in the United Kingdom.  Pin numbers relate to the pins in the socket.

Furthermore, a 12S socket is required in addition to either of the above when towing caravans.  This provides a permanent live supply in addition to auxiliary battery charging and switched fridge supply's.  The following is the standard wiring code which is used in the United Kingdom.  Pin numbers relate to the pins in the plug and socket.

Care must be taken when connecting into the vehicle wiring loom.  If your vehicle is fitted with a bulb failure system or computer you should contact us for advice before installation.
