You have a couple of options. If you want to change out your wiring completely, I recommend the Tekonsha ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT. This will give you the quick no-splice connections and the power wiring to your battery to allow you to keep your current European wiring and add the American style trailer wiring.

If you just want a converter adapter, you can use the European 7-way round pin adapter to American 4-way # 118710 only if you have the combined brake and turn signals.

If you have the European 13-way, you would need to do some wiring to make an adapter. You could make an adapter using a universal 4-way flat tail light converter like part # 119130, but you would need to find a European trailer side 13-way connector that can be rewired. Simply connect the blunt cut wires from the Curt # C56175 to the corresponding pins on the 13-way connector. The functions of the wires from the Tow Ready converter are listed below.

Red Wire - Brake Lights
Yellow Wire - Left Turn Signal
Green Wire - Right Turn Signal
Brown Wire - Tail Lights/Running Lights
White Wire - Ground

So I know the wiring harness you're describing, the 4-round, and there isn't an adapter to get it to go to a 4-flat. That's okay though because there is a really simple solution. What you can do is just cut off your round 4-way and add a…
