To determine if your 2022 Acura RDX has the 12-Volt Power Provision you have 2 options. First is contacting the service department at your dealer to have them tell you if you have the provision. Otherwise you will need to access the 8-pin connector inside your Acura to see if it has 2 red wires in the factory side of the connector. This connector is located on the drivers side above the rear portion on the rear fender(see image).

If you only have one wire you do not have the provision and will need the Tekonsha T-One Vehicle Wiring Harness # 118804.

If your connector has 2 red wires you do have the provision and will need the Tekonsha T-One Vehicle Wiring Harness # 118800.
