i'm not surprised.....the more complicated these cars get the less people are doing their own work.....i have a bunch of w211's and two of them have the massaging seats and two do not.....all 2005 model year cars.....1 e500 and 1 e320 cdi have them (and 1 or each do not have them)....
it would seem like the wiring would have to be there but i'm not sure if the modules have to be flashed or not.

keep us posted if you don't mind and good luck with the swap.....
