This is a very interesting and edifying PDF that explains the installation of the Painless After-Market Complete Wiring Harness that allows for the Drop-In application of the GM 4.8L, 5.3L, 6.0L Engines in what I would guess to be anything that has enough room for these engines to fit within.

But the cool part of this step-by-step instructional, is that even though it is NOT from GM... it goes into great detail with images and explanations of all of the electronic ignition harnessing and sensors that need to be dealt with... regardless of whether their PCM or the stock GM PCM is being used to make it all run right:

...and to be fair and not play favorites ...if the idea comes down to building up an Older Vehicle with any of these Later Model GM V-8 Engines... This video comes from a Custom Car Builder demonstrating the Complete Wire Harness Systems offered by "Kwik-Wire":
