I think you would end up either putting a US style plug on your trailer, or building a patch cord to adapt the US plug to the UK plug. The pins have different assignments (left turn, right turn, tail light, etc) but the concept is exactly the same. You would just have to wire it up.

That silver connector is called the trailer draw bar. The hitch has a 2" square receiver on the vehicle, and you insert a drawbar into that. It attaches with a heavy pin, which has a retaining clip on one end. When you remove the drawbar, you insert a blanking plug (one came with my hitch).

The drawbars are available here from BMW, or any trailer supply store. They come in different drops for different hitch ball heights. They have a hole in one end where the actual ball is attached. There are also different ball diameters (1.875", 2", 2.25", etc) Your Euro 50 mm ball is pretty close to a 2" ball. Not sure if anyone sells a 50 mm ball that bolts right on to a standard drawbar, but if so that would make it easier.
