Hello Joe,
Reconfiguration necessary.
The Euro headlight unit is just a simple bolt-on for any US pagoda.
You only need to remove the lower little bracket that holds the (US-) headlight door.
Other than that it is a plug-and-play with the existing wiring harness.
Since a (US-) 230 never has side marker lamps (not original to the car) it's a good time point to remove those as well if you had some.
Or, you have to electrically connect your side marker lamps to the parking light of the Euro unit, if you like.
But that would be a custom connection then.
Best,
Achim
