In order to determine the correct trailer wiring harness for your 2020 Acura RDX - the option for +12-Volt Power Provision or without - you can check out the 8-pin connector on the driver's side interior trim panel, like in the accompanying photo. To see how to access this you can take a look below at the linked installation instructions.

Once you see the 8-pin connector, check to see the number of red wires going INTO the connector.

- One Red Wire - Without +12-Volt Power Provision: T-One Vehicle Wiring Harness # 118804
