Hey Phil! You do not need a factory tow package to install a wiring harness on your 2024 Lexus RX 350. You can use the T-One Vehicle Wiring Harness # TK92KR. This plugs into the connection points in the rear cargo area and then a hot lead will run up to your battery. Once installed you will have a 4-way to power your trailer's signal lights.

Do you already have a hitch on your vehicle?

Hi Robin, Yes, I had a hitch on my Rx 350, and it's 2023. Does it still work? and do you have any instruction to install the harness on You Tube? Thank you so much, Phil

@Phil the same hitch from the 2023 will carry over. We have not had a chance to install this on that vehicle yet so we don't have a video. The instructions from Tekonsha are pretty good so I'm sure you can manage using those.
