Hey Corey, the hitch you would want for your 2013 Lexus RX 350 would be the Tekonsha kit part # 118252 which installs really easy without requiring any splicing. What hitch did you go with?

going with the Curt (C13143) - I noticed that the T-One video was for the factory tow package. I'm going to be adding this tow hitch to a vehicle without the factory tow package. Assuming the car won't have that easy adapter to plug and play would I need something in place of that to get everything up and running or something in addition to?

@Corey I believe you still have the harness despite that wording on our product page so what I would do is check out the attached install video where you can find where to look for the harness on your vehicle to see if it's there. It SHOULD be but let me know.
