Compatible RX configurations provide a factory trailer-light connection behind the driver-side rear bumper. The vehicle-specific harness plugs into that connection without cutting the factory wiring. We verify the vehicle has the required tow-package provisions before installation.

Connector Location: The flat-4 is rolled and stored inside the rear cargo area when not in use, then routed through the liftgate opening for towing.

1. Confirming Factory Tow-Wiring Provisions

Before installing the harness, we verify the RX has the factory connector and electrical provisions required by the exact-fit wiring kit. This prevents installing a connector that the vehicle is not configured to power.

2. Accessing the Rear Factory Connector

The factory trailer-light plug is located behind the driver-side rear bumper area. Its protective cap is removed and retained while the connector and surrounding wiring are inspected.

3. Plug-In Harness Connection

The vehicle-specific harness is inserted until the locking tab is fully engaged. No factory lighting wires are cut or spliced.

4. Protected Cargo-Area Storage

The flat-4 is routed into the cargo area and secured so it remains dry, protected, and out of the way when not towing. The flexible cable is passed through the liftgate seal only when needed.

5. Electrical Test and Configuration Check

We test running lights, brake lights, and both turn signals before finishing the installation. Some RX vehicles may require dealer programming before the factory tow-wiring output becomes active; if testing identifies that condition, we explain the required next step rather than representing an inactive circuit as complete.
