Not to inject any logic into the discussion, but when buying a new
trailer from Germany, why doesn't the buyer simply specify the wiring
and connector that he plans to use? You'd think that, for the price
being paid for the trailer, it would make little difference in the
overall cost. Heck, Spindelberger might even do it for free.

Used trailers come as they are. If you buy a new glider with trailer,
the trailer gets pulled to the glider manufacturer by a European car.
Once the new glider is loaded into the trailer, it is pulled by another
European car to the port for delivery. One needs the European wiring
to work in Europe until it gets to the port. I suppose that they could
put USA wiring into the trailer at the factory and then put the trailer on

a truck to get it to the glider factory, and then truck the glider -in -
trailer to the port, but that is a LOT more expensive than just making
up a pig-tail here. Besides, my pig-tail works for any of the 7 pin
connectors. I have probably used that thing on 10 different glider
trailers I have picked up at the dock. The reverse also worked for me
when I shipped my glider overseas for a WGC, as the trailer was
already (still) wired for their cars. That is where the logic is. The
rest
of the world doesn't conform to USA standards.... If you have $$ to
burn, yes go ahead and have the USA wiring installed at the factory,
and then pay out the nose for getting it all the way to the port...
