non litronic to litornics conversion, do i need anything else
 

I have an 02 boxster with out litronics, and want to buy OEM litronics lights, just the 2 healight litronics assemblies, do these just fit right in and work, or do i need any other parts, are they just "plug and play" any info is much apprecaited.

They will function as "plug n' play."

Sometimes if you buy them new they'll come with some added hardware that allows the low beams to adjust when the brights are on to fill the gaps.
