You dont necessarily need the whole computer, just the chip from the 350 to put in the computer. Also I don't think you'll need the fuse box I think they are the same whether its 4.3 or 5.7. You will need all the sensors for the engine and the injectors for the tbi. I'm not sure thats all you'll need though, someone else will chime in I'm sure.

Isn't 94 OBDI and a half? If so, I'd scrap the entire 94 wiring harness, computer and sensors and pull one from a 92 or later.

use the 350 knock sensor and throttle body w/ injectors and the rest of the sensors and harness off the 4.3, no need to swap out as TBI harnesses are the same. same sensor plugs, 2 injectors... need a chip from an earlier truck though with a 350 and whatever trans you have*700r4? - the 94 had the electronic trans and dont think that one will work.
