Do '87 & '88 V6 motors have similar or the same heater hose connections?

Yes. There should be a plug in the side of the water pump. Earlier cars (85-86) will have about a 3" piece of pipe.
The main external differences for the 88 are the alternator, oil pressure sender, and the mating connectors on the harness.
I would use the 88 stuff, including the harness.
The exhaust heat shields are different. The 88 alternator does NOT have a heat shield, where the earlier one will. The 88 has a shield on the corner of the trunk-side manifold, nearest the alternator. The 88 Y-pipe is also wrapped in thermal shielding, where the earlier one just has bolt-on shields.
Again, I would use the 88 stuff if you can.
(The trunk blower was deleted in the 88. Possibly because of this "improved" heat shielding.)
FWIW, the 87 will have "Fiero" engraved into the plenum, instead of a sticker, as the 85 and 86 had.
