Replacing compressor and air springs on 2003 H2

[wrangedog]

I just ordered and received a replacement air ride suspension compressor from Arnott Inc. and replacement air springs from newgmparts.com. Just a quick question, Is this going to be as simple as merely swapping out the parts or am I going to need to go to the dealer to get everything reprogrammed, calibrated or at the least have the trouble code reset? Currently the compressor does not come on and the ride height button just flashes. The "service air suspension" is also displayed. The replacement compressor is the dual compressor as opposed to the original single. Thanks to all for any help.
