Ok, so I had it roughly correct.
I will continue answering my own questions (most of anyway) on the wiring of the ARB and VIAIR compressor on this thread in case it helps anyone.
I was a tiny bit confused over what an isolation switch was, but essentially it is your compressor switch. I was able to verify this info in the sPOD tech video
I also dug up the schematics and cross validated them against my schematic that I drew of the former hookup. I am uploading the schematics I found online that I thought were helpful.
