Co part Supra almost done

[Detroit4.0]

I picked up 22 Supra that was smacked pretty good in the front , I bought a couple parts cars to fix mine.

I swapped in a 2020 motor and trans with matching ecu and bcm. What else from the 2020 donor car should I be looking to swap over .
Where is the immobilizer in these cars ? I’m able to swap over the radio and information screen . Trying to get it running before taking it to the dealership for any needed programming.
