heated seats--I know summer is coming but
 

Are all MB seats wired for heat, regardless if the option was picked to have heated seats?

I was thinking if that is the case to connect my front seats up for the winter.

I've got the 240d (83) and 350sdl (91) I would like to hook bck up.

I'm afraid not. I suppose that you could add that function to your seats, however. The heaters are small pads which are sewn into the pleats on the seat (under the leather/MBTex obviously). Seems like a lot of work to me...
