The current NX uses a passive powered trailer-light converter. The installation requires testing the vehicle’s rear lighting circuits, making protected signal connections, grounding and securing the converter, and adding an independently fused 12-volt power supply.

Connector Location: The flat-4 remains inside the rear cargo area when not in use and is passed through the liftgate opening only when towing.

1. Cargo Trim Access and Circuit Testing

We carefully remove the rear cargo panels needed to reach the lighting harnesses. Each signal circuit is verified with test equipment so the converter receives the correct left-turn, right-turn, brake, and running-light inputs.

2. Converter Signal Connections

The converter leads are connected to the verified factory circuits using protected, strain-relieved connections. The harness is secured to existing wiring paths rather than left loose behind the trim.

3. Module Mounting and Ground

The converter is mounted on a flat protected surface and grounded to clean body metal. Its location is chosen to prevent rattles and keep it clear of cargo-floor hardware.

4. Fused Power Lead Routing

A dedicated power wire is routed safely to the NX 12-volt battery. The lead is protected at body pass-throughs, kept away from exhaust and moving suspension components, and fused at the battery connection.

5. Protected Interior Storage

The flat-4 is stored inside the cargo area to shield its terminals from water, road salt, and impact. The liftgate weather seal allows the cable to be used without a permanent exterior opening.

6. Output Testing and Reassembly

We test all four trailer-light functions and verify converter power and ground before reinstalling the interior. This passive system does not require vehicle programming or active-module activation.
