Connector Location: The completed flat-4 stays inside the cargo area and is brought through the hatch opening only while towing.

1. Opening the Rear Cargo Area

The floor coverings, rear threshold, and the required side-panel fasteners are removed carefully to expose the factory lamp connectors without creasing the trim.

2. Installing the Driver-Side Exact-Fit Connection

The harness plugs are inserted inline at the driver-side taillight circuit. The powered converter is mounted securely behind the trim where it remains protected from cargo.

3. Routing to the Passenger-Side Lamp

The crossing lead is carried behind the rear threshold to the passenger side and connected inline. The harness is supported so it cannot be pinched by the restored trim or hatch hardware.

4. Adding Ground and Dedicated Power

The converter is grounded to suitable vehicle metal. A fuse-protected power lead is routed to the battery along a protected path away from exhaust heat, suspension travel, sharp edges, and normal service points.

5. Function Testing and Interior Storage

Both turn signals, brake lights, running lights, and ground integrity are tested before reassembly. The flat-4 is positioned near the center of the hatch for convenient use and protected storage indoors.

Protected Indoor Storage. The connector is not left hanging under the Tiguan, reducing exposure to water, road spray, and corrosion.
