oops almost forgot

I need one of those large round plug trailer brake setups for my prodigy controller and electric brake trailer

it looks like the bavauto kit is 200 $ does anyone know if that's complete and ready for a controller?


Or if the OEM trailer hitch kit with hitch + wiring is complete and ready for a brake controller?

looks like a royal pain to DIY it
