I don’t usually post on message boards but I found this post and I wanted to reply. Sorry if I am not following the forum etiquette.

I have done the halogen to xenon conversion on my car. I have a 2005. Let me tell you the way you are going results in an extremely expensive conversion. I had originally bought the oem kit with the headlamps, ballasts, bulbs, level sensors, wiring harness etc. I had someone work works at a dealer start putting in the parts and they realized that the computer that comes with the car is not compatible.

I am not one hundred percent sure how it works but I know he gave up on installing the retro fitted harness and just wired it directly somehow. I know the computer in the car also had to be re-programmed. The reason for this has to do with the car looking for the halogen current draw and having the xenon current draw. You will get the warning on the dash board saying that the front headlights are out and the computer will turn off the lights.

I can go on and on about all the problems we encountered...

Make a VERY long story short… I spent about 1500 in oem parts, and about 1500 in labor and I did get it to finally work with 100 percent oem parts. Best bet just go with an aftermarket kit and forget going oem
