392Hemi and 8HP70 swap 2018 PCM questions

YouTuber BoostedMotorsports put a Hellcat drivetrain in his Dakota. Don’t think he hooked up the ABS or anything and it runs fine other than some lights on the dash (he used the entire charger dash and IP). Based on this, I am guessing you could run most of an OEM harness and get it to work.

Only idea for a speedometer though is to find an aftermarket gauge that works with the factory CANBus system.
