GM-GMC: 05 Silverado climate control, dual climate, seperate unit

Question
I have an 05 silverado with manual dual climate controls and i was wondering if
it was possible to convert it to the auto controls if i got the seperate unit. If so,
is there any sort of wiring diagram i could get because i know there would have
to be some wiring involved im just not sure to what extent. thank you

Answer
I have never tried that myself but I would have to bet no.  There are temp sensors in various places that are not there on the manual systems.  The body control module is definately programmed different, if not completely different part no's.  I can get you the different wiring diagrams, but will need a place to email them to, as I cannot post anything like that on this site.\
hope this helps.
