Our wiring kits for the Volkswagen Caddy III Cross let you retrofit a towbar with road-legal lighting and vehicle-friendly integration. Choose vehicle-specific plug-and-play looms for quick installation or universal kits for flexible needs – perfect for trailers, bike racks and caravans.

7-pin or 13-pin – which makes sense?

7-pin: Covers core lighting (indicators, brake/tail); suitable for standard cargo trailers.
13-pin: Adds reverse light and permanent/charging power – recommended for caravans and onboard consumers.

Pro tip: If you want headroom for future use cases, choose 13-pin from the start.

Frequently Asked Questions (FAQ)

Should I choose 7-pin or 13-pin?
For basic trailers, 7-pin is usually sufficient. 13-pin is recommended for caravans, reverse light or additional consumers thanks to permanent/charging power.

Is control-unit coding required on the Caddy III Cross?
Depending on model year/equipment, diagnostic activation may be needed so that PDC muting, bulb monitoring and trailer features work correctly. Check the product page for kit-specific notes.

Will parking sensors (PDC) mute automatically?
Typically yes with vehicle-specific CAN-bus kits, provided the vehicle has PDC and the chosen kit supports it.

Vehicle-specific vs universal – which is better?
Vehicle-specific offers quicker installation and OEM-like integration; universal is flexible but requires more wiring work.

How do I get permanent power/charging (13-pin)?
Depending on the kit, additional cable, fuse and possibly a relay are included. See the item details or contact our support.

Is the wiring kit compatible with an already retrofitted towbar?
Yes, as long as the mechanical towbar is approved for the Caddy III/Cross. Match the socket carrier and loom routing with the selected kit.
