I am interested in what it would take to upgrade my E320 seats into E63 seats. My car currently has heated seats, and the E63 seats that I am interested in have both heated and ventilated.

I know I will need the switch in front of the CD changer and a new wiring harness. But will I need a new control box?

If anyone has added ventilated seats to their W211, any assistance would be great!

Have not done this on the E class...but generally the only thing you need when switching a seat via MB is a plug in and the switch. Usually the control is on the seat itself. This has been my experience so far.

Interested in seeing how this turns out for you.

There has to be another wire or harness for the cooling seat aspect. Since I only have heated seats there has to be another.

Yes, that is correct. MB most likely uses the same wiring harness for all E classes though...so the plug at the floor might be there and the control should be on the seat itself.

Since you have access to a E63...move the seats forward and check to see how many plugs are under there.
