Wiring Kits for Volkswagen T4 – reliable connectivity for your transporter

Looking for a suitable wiring kit for your VW T4? At Weltmann KFZ-Teile, we offer vehicle-specific solutions designed to perfectly match the T4’s electronics and body structure. Whether panel van, bus, Multivan or Caravelle – our kits ensure smooth signal transmission between your vehicle and trailers, bike racks or camping equipment.

Why a specialized wiring kit is essential for the VW T4

The VW T4 was produced in many variations and, depending on the year, features different electronic systems. A universal wiring kit is often insufficient to reliably connect all functions such as indicators, reverse light, fog light or permanent power. Only a vehicle-specific kit guarantees that the electronics work correctly and no error messages appear.

Which version to choose – 7-pole or 13-pole?

Your choice depends on the intended use:

7-pole wiring kit: suitable for standard trailers with basic lighting.
13-pole wiring kit: required for caravans, bike carriers with additional functions, or trailers with reverse light and charging capability.
