To clarify, I am using the BMW X5 to tow a travel trailer. I’m trying to install a brake controller in the BMW to control the brakes of the trailer.

I’m having trouble finding a brake controller for my 2025 BMW X5. When I find a brake controller, it seems that there are no wiring harnesses for the BMW. I had the towing package installed at the factory, so it seems that there should be a way to do it. Has anyone successfully installed a brake controller for this vehicle? If so, which one and how was it installed?
