this is the harness everyone is waiting for. This allows you to hookup any hitch because it uses the factory prewired tow connection which is the rectangle 8 pin. The other 3 grouped are for the computer and then circle connects to the pollak connector ( i am missing this but that what it looks like). Which is the tow connector 7pin US. I only paid 120 euro for the harness here in germany. My vehicle is a 2020 M50i US spec not euro. As I know i am the first to have this harness and will be the first factory retrofit but using stealth hitch because factory was ugly lol
