Question:
I appreciate the answer and the diagram, but I am a little confused about which wire from the trailer to connect to the appropriate wire on the new plug. The euro set up has one brake wire, while the American plug has a combined brake and turn for each side. Also the euro trailer has separate left and right taillight wires, and the US has a combined tail, license and side marker wire. I know ground is white for both, and I don't need the fog wire, but I am not sure which color euro wire to connect to the US wire on the plug.

Sure, you can cut off the Euro 7-pin and add an American-style 4-way. I recommend using the Wishbone Wiring Harness # A20WB, which actually has five wires; it splits the running light wires so you do not have to run a jumper wire from tail light to tail light.
You will need to do some splicing and you can use the accompanying diagram of a Euro 7-pin to see how they are typically wired. I recommend using butt connectors # DW05743-10 to connect the 20 gauge wires of the harness.
