If you just want running and brake lights without turn signals, buy a universal trailer wiring harness and connect it to a tail light wire. But to have turn signals, an adapter module is required because the universal U.S. trailer harness is 4-wire and the car is European 5-wire.
The European 5-wire system has wires for:
left turn
right turn
running lights
brake lights
ground
The U.S. 4-wire system has wires for:
left turn/stop light
right turn/stop light
running lights
ground
The converter module can be gotten here or from a NAPA store:
