AC/Heater Controls on 1994 Mercedes-Benz SL500

Can I replace the manual a/c / heater control in my '94 SL500 with the newer ('99+) electronic control unit? I really like the look and use-ability of the newer unit. Is this a "plug & play" switch? Thanks Shawn

In old cars it was simple to customize or swap parts from one year to another but the two items you want to swap will not be compatible.
