Euro lights need a 3 X 2 matrix plug.

Hint: You can find these on the tail light harness.

Either hit a pick n pull or get a pair from the dealer, or some ebay vendors sell them as mentioned above.

Five of the pins are used, the extra one is for the city lights.

You can figure out which wire goes where with a voltmeter.
