I pose this question because I have not had a chance to pull apart my car yet to check,..

I have a friend who has a 2004 coupe that has the older mirror HIDs, I have a 2006 coupe with the Projector bi-xenon HID's. He is wanting to swap his with mine, I am going to buy new ballast 6000k bulbs and new Lenses. Does anybody know if the 04 & 06 connecters are the same. He will be pulling the entire setup ballast and all.

 

First question, why would you want to downgrade your headlights. Second, looks like he is getting the best deal out of this instead of you, and to answer your question yes they are plug n play.

 

That's for damn sure!
Hey OP my 05 headlights are in mint condition, my car only has 17k miles. Let's swap. lol
