In order to install the Redarc Tow-Pro Liberty Brake Controller part # RED24FR on a 2019 Lexus RX 350 you'll need the following:
Universal Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers part # RED69FR
T-One Vehicle Wiring Harness part # 118252
4 to 7-Way with 4-Way Adapter part # ETBC7
The above will require splicing into the vehicle, the stop light circuit circuit in particular. It will also require drilling into the dash to mount the control knob for the brake controller. It is still a great option but for more infrequent towing I recommend the Curt Echo part # C51180 with 4 to 7-Way with 4-Way Adapter part # ETBC7L. There is no spicing or drilling for this option. Install is much easier.
We don't have exact install instructions for this vehicle but since the process is standard, you can look at pretty much any of the videos on the adapter for help.
