The DBW guys can chime, but I dont think you need an X link

All the rest of it is the same

Swap the motors already.

The only thing I would keep from the 5.3 and put it on the 6.0 is the throttle body and that's because of the TAC module.

Swaps right in the 05. Slap your 05 intake assembly on and everything else should plug right in

Default swap
I went from a 5.3 to a 6.2 in my 2010 and it
was a perfect PNP, used the 2011 Silverado
PCM OS file. downloaded from HPT file storage.

Check the alternator plug. Mine turned out different between the caddy and sierra.
