CRX climate control unit work in a Civic??

I'm thinking about putting a CRX climate control in my Civic. I know the CRX climate control has a few issues but the push buttons appeal to me. It looks like an upgrade. I would of course hold on to the Civic controls just in case I need to revert back. Assuming I have a CRX climate control head unit in good working condition, what else would I need? I see the CRX unit has one additional electrical connection and at least one less cable connection. I have the pigtails but I could use some information about what would I need to do to get this to work. I guess I also need the electric motors from the heater box and recirculation box, I don't have those yet are they reliable? Are they hard to get to? Will they bolt right up to the Civic? I have the factory manual for my Civic but I think I could use a wiring diagram for a CRX, can someone point me to one?
