I have not seen a A to Z instruction set or video on the process, just bits and pieces of forum posts and other videos of people doing Hemi Swaps.
You might find more info on the Wrangler JL side that should be pretty much the same or similar.
My take it is pretty much a tribal knowledge type thing with many just disconnecting what comes out of the cab firewall like the steering linkage, brake boost, parking cables and pulling back the wire harnesses off the engine bay firewall.
Board vendor Northridge 4x4 does a few cab off Hemi swaps and they may be able to give you a primer overview on what is involved.
