To add a wiring harness to your 2022 Lexus RX 350L you will need the Tekonsha Upgraded Modulite Vehicle Wiring Harness Kit w/ 4-Pole Trailer Connector and Installation Kit item # C59236. This is the only wiring harness available for your Lexus since it does not have the tow package. It works with either LED or incandescent bulbs on both the trailer and vehicle. The taillight circuit has been upgraded to work with vehicles using PWM, allowing converter to turn on fully giving trailer maximum light brightness.

To round out your towing setup I recommend the Curt Towing Starter Kit for 2" Hitches item # C45534. This towing kit will provide you with a 2" ball and a fixed ball mount with a 3/4" rise and 2" drop. It also includes a hitch pin and clip, hitch receiver lock with keys, hitch cover, and a storage case.
