Questions on 5.3LS Swap in 88 Wagon

I found a 2003 suburban with 5.3 and 4l60e

I asked the guys to pull the complete engine harness, manifolds, radiator, radiator shroud, fuel pump, fuel tank from it.

Can I even use all that stuff? I wasn’t sure so I tried to get everything I could.

Also I want to use a 4l80e - can I use the harness and trans from another GM and plug it up to the 5.3 or do I have to have an after marker harness?

The existing 5.3/4l60e harness needs reworking to use stand alone and modifications for a 4l80e vs. 4l60e
Depending on year of "4l80e" harness you want to swap/use it may work or require reworking.

clear as mud?
