Went from single to the dual air compressor. NEED HELP!

I have a 04 h2 single compressor went out so I bought a dual one fronm arnott installed it I can get everything to fuction with my snap on scanner ( open, closing of selnoids) except the compressors will not turn on. I am using my old module. Arnott said that it had to be programmed however my old hummer dealer says they have no way to do it. Does anybody know about this? Should I just buy a new module a 89060585 gm part number do they come programmed already. will that fix my problem?

Found a tech bulliten says to connect pins 23 and 24 together at the control module if you have the old on and converting to the new dual compressor. did that and now I have no control with the scan tool says it can't commuicate. I also don't get the service air suspension on the dic. Anybody have this before?
