Difference between -01 and -02 engine ?

Megabusa Sweden

I have changed my engine from a -01 to a -02. I am using the sensors from my -01 including the ECM, but forgot to change the crankshaft sensor, is that a problem or are they the same ?

The thing is that the engine is in a car and I need to use the -01 wiring harness. So for using the -02 engine what parts are the same and what parts need to be changed ?
