The 2001 and later Mk2 996 headlights are not the same as a Boxster or earlier 996s , and have a different bumper line than previous models. Earlier 986s and 996s are the same except i discovered the hard way that the 996 has a shinier cross pattern inside the light housing where as the 986 Boxster has straight lines and a less reflective surface inside.
The litronics are just plug in and play but if you want the touted self leveling feature there is some extra wiring and a module required that sells for a couple hundred bucks.
