With a 02 PCM you will need a 02 harness, unless you want to repin almost every pin in the 98 harness connectors, then there will still be some issues. It would also help to know what MY vehicke you are putting the 02 engine and PCM in.

I think the 98 body harness will work, as long as you use the 99-02 engine harness. Someone can correct me if I'm wrong.

I have seen a automatic transmission destroyed in this situation the sensors,harness and computer were not the same. Maybe check with Speartech or painless wiring.
