Euro headlight wiring for W123

I did some digging using the Search tool but I wasn't able to find any information on wiring euro headlights on a U.S. W123.

I won't have a problem with figuring out the wiring codes, but the U.S. lights have a 4 pin connector where the new euro lights have a 5 pin connector. Anyone know where I can get the new connector?

I imagine that I could just pull out the female pins from the U.S. headlight connector and connect them directly to the 4 male pins on the euro headlight, and that would give me high/low/fog/ground. I could then just make a jumper from the parking lights to the euro city lights. I'd like to do it right, though, and that means getting the euro connector.

Thanks!
