95 motor, PCM/harness should work fine.

Use the harness for the car you have. The engine and body harnesses will plug together but the wires are not all in the same spots in the connectors. You can use either pcm with the harness just make sure you have the correct knock sensor in the block for the pcm you're using.

You can find any differences in the charts on my Tech Page. Very little is different.

If the 97 once had a LT-1 in it, just use that wiring and PCM.

Like Rob said, 95/PCM/Engine harness should be fine. Rob differences in the Dash harness that may affect him?
