what will i all need to put 06 headlights in my 02 and make everything functional............is the wiring different?

 

Should fit. One part is a little different but it's supposed to be easy to make work. I think there is a DIY but not 100%

 

do i have to get new ballist?

 

I just got done doing the ap2 conversion on my02. You dont have to get new ballast but it does make things alot easier because thats whats diffrent on the housing the 02 wiring is to big for the hole so you have to dremmel it. Look at the DIY on top of this forum trust me it helps.
