The Volkswagen Caddy III Maxi (LWB) offers extra space – and with the right wiring kit you’ll get road-legal trailer lighting and reliable vehicle communication. Choose vehicle-specific plug-and-play looms for a clean, fast install or universal kits for special setups. Every set is designed for compliant lighting and stable CAN-bus interaction.

7-pin or 13-pin – what’s best for the Maxi?

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

Pro tip: Choose 13-pin if you want future flexibility and use adapters when needed.

Bulb failure monitoring (Check-Control) retained where fitted.
Automatic PDC muting in trailer mode when supported by vehicle/kit.
ESP/trailer stability supported if available on the vehicle.

Installation notes for the long wheelbase

Vehicle-specific looms use model-matched connectors and OEM-like routing. On the Maxi, cable routing/length can differ due to the extended body; compatible kits account for this. Skilled DIYers can complete the job; for permanent power/charging lines (13-pin) and diagnostics/coding we recommend a professional workshop.

Any differences vs the Caddy III short wheelbase?
Electrically the platforms are often similar; on the Maxi the cable runs/lengths can differ. Always check the kit’s specifications.

Is coding mandatory?
Depending on model year/equipment, diagnostic activation may be needed so Check-Control, PDC muting and trailer features work correctly.

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

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