My 2007 Aspen didn't come with the digital temperature control. I see a few on ebay is it a simple plug and play install?

 

This is something I am highly curious about myself. My Accord has the digital Auto temp feature and I love it. Set the desired temperature in degrees and it automatically adjust hot/cold and fan speed. Only thing I think would hinder this swap is the dual zone front (Driver/Passenger) which is on the digital one but not on the manual one.
