Hey,

I've gota 2001 GMC Sierra SLE Z71. The current Air Conditioner is the factory with 3 knobs, the usual. I found a digital climate controlled cluster on ebay. I removed my old A/C and saw that there's only one major connection on the back of the panel. Will the new digital A.C. panel work? Or is there something else I would need to get to go along with it.

Thanks, brent
