X7 M50i with factory hitch, controller plug?


New to your forums.

I have an 2020 (built Feb 4) X7 M50i with the factory trailer hitch. I need a trailer brake controller. The contraption BMW sells as an accessory is this ugly looking cup-holder thingy.

Does anyone here have experience with this accessory?

Does it plug into a socket under the dash (if the factory hitch is installed) ?

If there is is controller plug under the dash, where is it and what is the pin-out?

Best regards,
