The TX uses an interior factory connection behind the driver-side third-row trim and a separate exterior jumper behind the rear bumper. A powered converter is connected and secured inside the vehicle, while the flat-4 is routed outside and mounted beside the hitch for immediate access.

Connector Location: The completed flat-4 remains outside the vehicle beside the hitch. It is not stored loose in the cargo area.

1. Accessing the Third-Row Connection

We fold the second-row seat forward and carefully remove the driver-side third-row cup holder, fastener cover, and only the trim needed to reach the factory wiring connector.

2. Connecting and Securing the Converter

The vehicle-specific harness plugs into the TX factory connector. The powered converter is mounted below the armrest area where it will not move, rattle, or interfere with the trim when the interior is reassembled.

3. Factory Ground Connection

The harness ground is secured at the existing grounding point behind the rear seat-belt area. We verify clean metal contact and a tight connection before concealing the module.

4. Exterior Jumper and Connector Routing

Behind the driver-side rear bumper, we remove the factory dust cap and connect the exterior jumper. The flat-4 is routed to the center of the vehicle and secured beside the hitch, away from the exhaust and moving suspension components.

5. Electrical Test and Interior Restoration

Running lights, brake lights, left turn, right turn, and ground integrity are tested before the cup holder and trim are reinstalled. The final harness is secured against movement and the exterior connector receives its protective cover.
