Engine harness should be the same. Double check to make sure they have the same color ECU connectors and the same emission equipment. There were a couple changes on the engine in the 2002/3 timeframe.

I just compared the pinouts. They're real close, but I found a couple differences. I think it's because the 03 has the PCM controlling the alternator, but the 02 doesn't.
If you're handy with automotive electrical stuff you could probably add those couple wires.
I'd post the pinouts, but they end up so small on here you can't read them and they're 4 big pages each. Not to mention posting copyrighted material.

Another thing I'm wondering is the 03 has a different ecm than the 0411 in the 02 that's recommended for swapping, and can it be re-lfashed successfully with the 0411 flass?
