Wheel for a 2006 M-Class..l, currently do not have this option, but was able to pick up a new heated steering wheel, and was curious to see what is involved and needed to install.. l also have the telescopic stalk with the light in the end, to replace the other stalk...l'm assuming thier must be a control unit somewhere, probably in the steering wheel column somewhere ??? How about the wiring harness ???? Or would it be their already ???? Any thoughts would be greatly appreciated..Thanks.....
