You turned something straightforward into a sh!tshow electrical nightmare. U codes are module communication problems. As per any reference I have, U1416 doesn't exist for Mopar. You sure it isn't P1416?
You LITERALLY should have just dropped it in and hooked everything up and it would've been fine. That engine didn't need the donor electronics smh.

I'm sorry, I sit corrected. I could have SWORN your post said 07 hemi into 06 hemi (people actually HAVE complicated that swap). Ok, yeah no that's a pain in the d!ck. Like I said, U code is module communication. C2202 would have posted the minute you plugged the PCM into the bus and powered it on, unless the PCM was reflashed prior to installation. Even then, any other module that communicated the wrong VIN to it will trigger that code.
I'm glad you clarified that, because I'm going to use this as a good example of why not to do this. FYI there is a possibility that you might not ever get rid of these specific codes.
