I would snag the entire under dash & engine harness intact from the Z/28. You can sort out what isn't needed after you get the thing into the truck and wired up.

There isn't much length to the stock harness since the PCM is mounted to the inner fender so you are kind of limited as to where it will fit without a bunch of wire extension & soldering. I blended two harnesses together to get the PCM under the dash in the 91 RS swap. Quite a lengthy process but worth it to clean up the engine compartment.
