When installing a trailer wiring harness on your 2021 Subaru WRX The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56259 is confirmed to fit your vehicle. This 4 flat harness will connect to your rear tail light, and everything will work correctly.

The wiring has a plug and play installation that plugs into the vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will also have to run the hot lead up to the car's battery.

I attached an installation video link below.
