Gathering parts , have a question

[kwin]

So far I have a 2006 5.3 and harness, a 2000 harness and computer , motor mount plate adapters , flywheel spacer is ordered ....

So here is the question, will the 2000 computer work with the 06 harness and engine, my cousin has the entire EFI live suite and will take care of the programing changes but he is not around right now and I need to know if I need to look for a new pcm.
The pcm I have is from a 6.0.
I plan on using the 2006 harness and am hoping to delete the wired throttle body , I have already picked up a cable throttle body.
Thanks for taking the time to read my post.
