Our wiring kits for the Volkswagen Caddy IV connect your towbar to the vehicle with road-legal lighting and BCM/CAN-bus friendly integration. Choose vehicle-specific plug-and-play looms for a factory-like fit, or universal kits for special setups – perfect for trailers, bike racks and caravans.

7-pin vs 13-pin – choosing the right setup

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

Pro tip: If you want future flexibility, go 13-pin and use adapters when needed.

Frequently Asked Questions (FAQ)

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

Is control-unit coding required on the Caddy IV?
Depending on model year/equipment, 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 (PDC) mute automatically?
Typically yes with vehicle-specific CAN-bus kits, provided the vehicle has PDC and the selected kit supports this function.

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

How do I get permanent power/charging (13-pin)?
Depending on the kit, additional cable, fuse and possibly a relay are included. Refer to the product description.

Can I install the kit myself?
Yes, with auto-electrics experience. For permanent power runs, charging line and coding we recommend a professional installer.
