Has anyone attempted to marry a 2007 - 2010 JKU dashboard harness to a 2020 (and above) 6.4l Hemi engine wiring harness using a late model PCM?

I'm new. I'm not looking to purchase a swap kit. That's too easy
 
I have a jk harness, a factory 6.4 Hemi harness, and a 2020 PCM from a Scat Pack. My goal is to make the necessary modifications so everything will talk.
