I have spent some time looking through the archives and am not able to understand how the setup goes. Forgive me for my ignorance

I would appreciate it if someone can explain to me the way to have it set up.
I recently found a great deal on a pair of new euro headlights for my car and sent a bank wire transfer to the seller in Germany. I should have it in maybe within a month or so. I am guessing late March? So I am trying to have everything set up so when the time comes, I won't be confused.
I read in the archives that the connection plug is different than the US version. Someting like a 6 point plug to a 5. I read some people where able to convert this. My first question is, how do I convert the plug.
Then, I would like to have the city lights set up as well. What would I need for that? I read in the archives someone added a 6inch wire or something to that extent to have it work.
I don't like the US wipers, how they look and that the stand up in an upside down "L" shape. I would like to know how to convert my US wiper assemblt, including the motor, into a Euro one. I read in a thread, a member(sixto) knows an individual who has successfully did just that. I also understand that the wiper motors on the Euro and US work in opposite way. So can I just put the right US motor to the left headlight and vice versa? Then just find the actual Euro wiper arm? If this is possible, where would I be able to find a Euro wiper arm, new or used?
Please let me know since I am still lost. I will be looking again in the archives shortly. I am thanking you all in advance for any help I recieve.
