I was looking at the title of your thread (gen1 to gen2 swap) & I am pretty sure that the '96 is also a gen 1. Meaning that you are doing a gen 1 to gen 1 swap, which may simplify matters and mean that you MAY not have as big an interchangeability issue with PCMs and wiring harnesses (as far as the years go). (However, in the engine swapping game, nothing is a sure thing, and there may be some variations within the gen1 years.) And I would agree that the wiring harness and PCM should both be for a 5.2 and you MAY need to get the PCM flashed for your VIN, or possibly a flash for the swap . . . I do not know how sophisticated the Dak PCMs were back then.
