95 PCM controlling a 93 LT1

What all has to be done to swap the PCM out for one from a 94-95 so I can tune it? I know the 93 runs speed density and all that other stuff but will the connectors interchange or do I need to get a whole harness from a 94-95?

You will need a new engine harness at the least. The connections at the computer are even different.

The 95 has some different tranny stuff too from the pre 94's. Unless ur running a T56. A 95 computer will search for TCC signal.
