I can't see why not, it's the same body style so I doubt they did any major changes to the wiring harness.
Yes its a bolt up deal. engine blocks are the same, mounts to the engine/trans are the same. Is the original engine carb or efi?
Should bolt right in...a few plugs on your harness might be different, but thats nothing to fix. One more thing to check too...check the injector plugs as well too. My truck is a 91 & Ive got a motor out of a 94 & I had to switch the injectors back to the ones from the 91 cause the plugs were different.
