Fitment guarantee and VIN verification

Every harness offered undergoes a detailed visual inspection and circuit continuity test – we guarantee no cut wires or damaged connectors.

Fitment / installation tip: The initial designation 4K1 (electrical system group 971 / 139) defines the vehicle cabin harness with left-hand drive. The version sourced from a highly equipped US vehicle is an ideal base for restoring vehicles imported from the United States after interior damage or flooding, as well as for advanced equipment projects (e.g., Retrofit panoramic roof, 360° cameras, or laser lights), where the standard, lower-specification European harness does not have the pins and CAN/FlexRay/LVDS bus wires routed. All plugs and conduits have factory markings that facilitate error-free routing of the installation in the factory floor channels. Before purchasing, we recommend comparing the exact letter suffix on the identification sticker or verifying it using the vehicle's VIN.
