The current RX uses a passive powered converter rather than an active, programmed towing module. We identify the required lighting circuits at the rear of the vehicle, make protected signal connections, and supply the converter through its own fused battery feed.

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

1. Rear Trim Access and Circuit Identification

We remove only the cargo-area trim needed to reach the rear lighting harnesses. Each circuit is tested at the vehicle—left turn, right turn, stop, and tail—so the converter is connected to verified signals rather than relying on wire color alone.

2. Protected Signal Connections

The converter input leads are connected to the identified lighting circuits and individually insulated. The harness is routed along existing wiring paths so it remains clear of sharp edges, latch hardware, and moving trim.

3. Converter Mounting and Ground

The powered converter is secured to a flat protected surface behind the cargo trim. Its ground is attached to clean body metal and checked before the module is concealed.

4. Dedicated Fused Battery Power

A separate power lead is routed from the converter to the vehicle’s 12-volt battery. The wire is protected at every pass-through, kept away from heat and suspension movement, and fused at the battery connection.

5. Interior Connector Storage

The flat-4 is coiled inside the cargo area where it stays dry and protected from road spray. When needed, the flexible cable passes through the liftgate weather seal without altering the bumper.

6. Functional Test and Reassembly

We test running lights, brake lights, both turn signals, converter output, and ground integrity before reinstalling the trim. No programming or active towing-module activation is required.
