A vehicle-specific electrical kit is one specially constructed with the right cable lengths and functions and usually equipped with original plug connectors. In the case of electrical kits with vehicle-specific connectors, simply remove the tail light connectors and lay the lead between them. This way you will have an optimal function and a safe electrical connection using the original connectors and contacts.

The assembly manual for a vehicle-specific electrical kit describes the fitting steps required for the respective vehicle and helps keep the fitting time to a minimum.

A 13-pin electrical kit is pre-equipped with an interface for additional power supplies and is delivered with a 13-pin socket.

Unlike the 7-pin electrical kit, the 13-pin kit enables the transfer of all lighting and additional functions. All additional functions, such as controlling trailer reverse lights, additional power in a camper (e.g. refrigerator) or for mounting a rear cycle carrier etc. are warranted with just the one connector.

The law requires a C2 indicator lamp to monitor the flashing lights of the trailer and shows the driver if the trailer indicators are working.
The C2 indicator lamp must been within the driver’s field of vision, blinks in rhythm with the trailer blinking lights and so signalizes their function to the driver.

The acoustic indicator warning sounds in rhythm with the trailer indicator lights and so signalizes their function to the driver.
Advantages: No work on the dashboard necessary, less assembly time.

The Check Control system, also known as light failure indicator or monitor, is a component of the vehicle electronics and monitors various functions of the vehicle when in operation, for instance full beam headlights, brake lights or rear fog lamp.

If the lighting fails the driver is notified either by an acoustic warning signal or an optical symbol; with a board computer digital information will be shown.

A parking assistance system helps the driver park by means of optical or acoustic signals.

With most electrical kits this parking assistance system is automatically deactivated to avoid any misinformation. This switch-off function can be regulated via the micro-switch in the socket or via the control device.

If a vehicle is equipped with a modern CAN data bus (Controller Area Network), the information exchange within the on-board vehicle network is carried out on a digital basis and not, as is usual, on an analogue basis. To process these digital data and transfer the information required for the trailer operation the electrical kit must have a corresponding CAN data bus trailer module, so that all functions (reverse lighting, indicators etc.) required for the trailer can be controlled.

A vehicle equipped with a CAN data bus must almost always be activated for towing.

Universal electrical kits can, as a rule, not be used in vehicles equipped with a CAN data bus.

In the case of modern vehicles, in particular those equipped with a CAN data bus, the vehicle almost always has to be activated for the towing function. Please refer here to the car manufacturer’s operation manual.

The activation of a vehicle for towing can, as a rule, be carried out by any qualified workshop.

The fitting times given are non-binding reference values in minutes.

These specifications can vary depending on various influences, such as the experience of the fitter, the level of equipment or condition of the vehicle. In any case, the operation instruction manual of the vehicle (trailer) should be consulted before beginning with the fitting.

Towbars and electrical kits are safety components and should only be fitted by qualified personnel!
