Our wiring kits for the Volkswagen Crafter connect the towbar to the vehicle electronics with either vehicle-specific looms for a factory-like fit or universal kits for special bodies. Whether panel van, crew bus or chassis cab, the right kit ensures road-legal lighting and fault-free communication with the vehicle.

7-pin or 13-pin – what suits the Crafter best?

7-pin: Core functions (indicators, brake/tail) – suitable for basic cargo trailers.
13-pin: Adds reverse light plus permanent power (Pin 9) and charging line (Pin 10) – recommended for caravans and powered accessories.

Pro tip: For commercial use, 13-pin is usually the future-proof choice.

Crafter-specific integration & features

CAN-bus/BCM interface for clean integration without fault messages.
Bulb failure monitoring (Check-Control) retained where fitted.
Automatic PDC muting (front/rear) and possible rear-camera logic in trailer mode (kit/vehicle dependent).
ESP/trailer stability supported when available.
LED tail-lamp support on many vehicle-specific looms (load simulation may apply – kit dependent).
Rear fog cut-off may be provided to prevent glare (depending on kit).
Coding/activation: Depending on model year/control units it can be recommended or required (e.g., BCM/gateway).

Installation & notes

Vehicle-specific looms use model-matched connectors and OEM-like routing. For chassis-cab/bespoke bodies, cable length/routing can differ – compatible kits account for this. For permanent power/charging (13-pin), kits often include wiring, fuse and relay. Skilled DIYers can complete the retrofit; for diagnostics/coding we recommend a professional workshop.

Frequently Asked Questions (FAQ)

Should I choose 7-pin or 13-pin?
For basic trailers, 7-pin is enough. 13-pin is recommended for reverse light, caravans and powered accessories via permanent/charging lines.

Is coding required?
Depending on model year/control units, diagnostic activation may be needed so PDC muting, bulb monitoring and trailer features work correctly. See the product page for kit-specific notes.

Will parking sensors mute automatically in trailer mode?
Typically yes with vehicle-specific CAN-bus kits, provided the vehicle has PDC and the selected kit supports it.

Are these looms compatible with LED tail lamps?
Many vehicle-specific looms are LED-ready; some include load simulation. Please check the item details.

How do I get permanent power/charging (13-pin)?
Kits commonly include the additional cable, fuse and possibly a relay. Refer to the installation notes.

Differences between Crafter generations?
Interfaces and coding requirements can vary. Select the exact variant/model year and review each kit’s specs.

Will the kit work with an already installed towbar?
Yes, provided the mechanical towbar is approved for the Crafter. Ensure the socket carrier and loom routing match the selected kit.
