As you're a North American resident you're really only going to be able to source the correct replacement in North America. European-market cars with the five lamp taillights had the reversing (back-up) light mounted in the top row and a rear fog light, with a 21-watt bulb, where the North American-market models had the reversing light (i.e mounted vertically and closest to the car's centre-line). This almost certainly accounts for the different wiring looms.

You could replace both lamp assemblies and modify the loom to suit the European-spec light-clusters but I'm not sure if your state's DoT would accept the modification, as the clusters would not be American Type-approved.

If you do go down that route the upper lamps are 21-watt for turn signal and back-up, while the lower are a 21-watt stop and 5-watt rear. Don't connect the rear fog unless your state's regulations allow it.
