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.

 

Thanks Shoe!

 

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.
