You are looking for the rear tail light fuse on your 2021 RX 350. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # C56217 connects in line with your rear tail lights to power your trailer harness. I have attached a picture of the fuse box cover for your vehicle. The fuse is marked tail and it is 8 down on the right hand side of the diagram.
