Seat question RE: seat heater elements

[MikeTangas]

Here's my dilema, I stopped by my favorite salvage yard today and they recent obtained an '87 420SEL in the same color combo as the 560. This car has a shade over 100K on the clock at the time of wreck and the interior is nearly flawless. The leather feels like a brand new pair of gloves, soft and supple, no cracks scratches or tears, stitching is tight. The car was not equipped with seat heaters.

I have the opportunity to get these seats for next to nothing, barely even a song.

Is it possible to simply move the heating elements from my existing seats to the 420's? If so, what is the best way to accomplish the task? Or would I be better off skinning the 420's seats and moving the hide to my existing seats?
