I have a low mileage lt1 drivetrain that I'm thinking about swapping into a 96 ss. I'm swapping the entire wiring harness and pcm from the 95 over as well. I also have a z28 cluster that is made for the 95 that I'm swapping over as well. Now my question is, besides the obd2, are there any difference between the years? Would the 95 harness plug in under the dash? Would the z28 cluster work the same? Can I replace the obd2 diagnostic plug with the obd1 plug?
