ok, so i did a little exploring inside and under the seat. i unhooked the airbag and got power to each actuator. one controls the headrest, one controls the seat back tilt, one controls the seat height, one for the forward/backward movement, and one for the the bottom part of the seat where your upper leg is. i see some other wires too. one goes to an under seat light and two sets go through the middle of the seat cusion. i'm guessing these seats are heated? maybe someone can tell me some details about the different types of seats in the e-class? are they all the same, besides color? all they all heated? messaged? sorry for the long post, but i want these to work. thanks.
