2003 Truck, 04.5 Engine

[MHDiesel16]

Has anyone swapped an 04.5/05 engine into an 03 truck? Is there quite a bit that needs to be changed around to make it work properly?
The only reason they are wanting to do it, is because the 03 engine is bad and they happen to have a complete 04.5 truck that was wrecked.
I appreciate any input.
Thanks!

Biggest difference is the wiring harness/ECM needs swapped and the turbo needs swapped, but you could run the later turbo with a boost fooler.
Also, watch out on the '04, it could have the in-tank fuel pump conversion, but then, so could the '03.
