Find towbar wiring kits by Mercedes model

Browse the model groups below to find information for your Mercedes. Where a separate body-style, Hybrid or electric page is listed, choose the one that matches your vehicle. Confirm the generation and production date against the individual kit's application details before ordering.

Compact models: A-Class and B-Class

C-Class models and variants

Choose the C-Class page that matches your body style and powertrain. All-Terrain, Hybrid and Sport Coupe applications are listed separately.

E-Class, CLA, CLK and CLS

Mercedes SUV models

Select the exact model and generation. Use the separate GLC Hybrid page where it matches your vehicle's powertrain.

Mercedes electric models

Explore the model pages below, then confirm the exact vehicle's towing or carrier approval and the selected kit's application details.

Mercedes vans, MPVs and pick-up models

Match the model and body configuration to the kit documentation, including any specified wheelbase or factory towing-preparation requirements.

How to choose the right Mercedes towbar wiring kit

Use the model overview to narrow your search, then check the following details for the kit you are considering:

Model and generation: match the exact Mercedes model and generation covered by the application. A model badge alone may cover several different vehicle platforms.
Production date and body style: check the application dates and whether the kit covers your saloon, estate, coupe, SUV, van or MPV configuration.
Powertrain and factory equipment: confirm the engine or electrified derivative and any specified towing-preparation requirements.
Socket and electrical functions: match the trailer, caravan or cycle carrier's connection and check the lighting and power circuits included with the kit.

Confirm the permitted towing weight and nose load in the vehicle documentation. A wiring kit provides the electrical connection; it does not increase the vehicle's towing or load limits.

7-pin or 13-pin towbar electrics for your Mercedes?

The socket choice depends on the equipment you plan to connect and the functions it needs.

7-pin electrics: provide basic trailer lighting, including indicators, brake lights, tail lights and a rear fog light. Check that the connection covers all lighting functions required by your trailer or cycle carrier.
13-pin electrics: include a reversing-light connection and can accommodate additional power circuits. Check whether permanent and switched power feeds are included or require an extension kit for your chosen application.

An adapter changes the plug connection but cannot add electrical circuits missing from the installation. Read our towbar electrics guide for more information about socket types and adapters.

Mercedes vehicle functions, coding and installation

Check the selected kit's documented support for trailer detection, parking sensor management, rear fog light cut-off and trailer-related vehicle functions. Their availability and operation depend on the Mercedes platform, vehicle equipment and the wiring kit.

Follow the application-specific fitting instructions for connections, power supply, cable routing and any required coding. Complete the specified lighting and functional checks after installation and activation. Further guidance is available in our towbar wiring installation FAQs.

Choosing towbar wiring for a hybrid or electric Mercedes

For C-Class Hybrid, C-Class All-Terrain Hybrid, GLC Hybrid and the electric models listed above, match the exact powertrain to the kit application. Confirm that the vehicle is approved for the intended towing or carrier use, and follow the relevant vehicle and fitting documentation. A model page is a starting point for selection; the individual vehicle and kit specifications determine suitability.
