'03 Gauge cluster replacement

I tried to do a search on this subject and Google has too much internet "noise" and ads to sort through these days. My friend's '03 2500HD with 6.0L/ Allison trans has failing gauges. I thought maybe I'd try to chase down this problem and ask on this forum. If I find a replacement are they, "plug and play" or does the odometer have to be programmed independent of the ECM? Is there anything else to be aware of?
