Hello Tim, thanks for reaching out. For your 2022 BMW X3 with the factory 4 and 7 way, I recommend the Redarc Tow Pro Liberty # RED52VR. This is a really clean solution because the main unit mounts behind the dash and the only visible piece is the small LED control knob. It blends in nicely with the interior and gives you smooth, proportional braking that automatically adjusts to your braking pressure. It is a great fit for a smaller trailer and keeps everything looking OEM.

Since you already have the factory 7 way, you are in good shape on wiring. Beyond the controller, you will just need the correct ball mount. The etrailer Adjustable 2 Ball Mount # e66PR is a solid option because it includes both a 2 inch and 2-5/16 inch ball and offers up to 6 inches of rise or drop, so you can dial in a level trailer.

What kind of trailer do you have?

@TimF Nice! That is a slick little camper. I love that big front facing window. The parts I mentioned will work great for that! Let me know if there is anything else you need.
