There is a company in Canada that builds the kits to do this that I have heard a lot of great reviews on. The last swap I did was on a cascadia with a dd15, we pulled it and put a ddec4 60 series back in. I ended up building a stand alone harness for the engine and making my own harness to operate the a/c, I then built a digital gauge cluster for the truck. Doing it this way is much easier than you would believe and I couldn’t imagine it would be too hard on a Cummins….. especially in an older truck.
If there is any way I might could help you figure out any of the things you may need to do just shoot me a pm with some contact info.
