Well I have already converted all the lights inside my car along with the ash tray and lighter plus I have made my needles, indiglo needles. Was very simple and easy. I have a write up on my webpage with the information needed to do the conversion. it's very simple. all you have to do is remove the center vents, do a few things here and there and your done. it's very easy and simple. the cruise control buttons, hazard button, rear defrost button and the others are just like the AC button. here's the webpage if you wanna get a write up. http://importenthusiasts.da.ru
