Climate Control 98 Accord

I currently have manual climate controls in my LX, and I was wondering how hard it would be to put in the automatic climate controls. Is it as simple as replacing the panel with the new dash, or do I have to run new wiring to the computer, or does it require a whole new computer for an EX. Thanks.

sorry to bring this topic up from way back when, but i was wondering the same thing. does anybody know where i can find wiring diagrams for both teh manual and automatic climate controls?
