Default 2003 6.0 in a 1999 4.8?

Didn't find the info I needed in the threads. I have a 99 1500 rcsb 3:73 4x4 with 4.8 144k miles. My buddy is parting out his 2003 2500 with 105k miles. Since 03 is drive by wire, what do I have to do to drop this engine in my truck? I don't want drive by wire.

Swap throttle bodies and retain your harness

All you do is strip the 6.0 down to a longblock and then bolt everything from your current engine (intake, accessories, etc) and you're done.
