2023 M3P trailer wiring harness

[trunkmonk3y]

After doing a ton of research, I'm still not completely understanding the options for trailer wiring on a 2023 M3P. I know I can definitely use a Tekonsha 119251, but the install is a little messy. Have to pick up +16v battery somewhere. The other option which I'm not sure on, is plugging into a possibly existing 3 pin (Canbus + power?) connector that exists for the sole purpose of trailer wiring. Something like this, and presumably there might be an impossible-to-obtain OEM version. Its spendy, but also a ton cleaner/easier to install.

Anyone install trailer wiring in a 2023 that has some insight?

They specifically exclude the 2023's in their wiring harness kit, but not the hitch, which makes it even more confusing. (Guessing whatever wiring kit they sell isn't 16v compatabile)

The wiring harness kit works fine in my 2023 M3 SR! And I have the 16V batterie system
