HI,

I am sorry that you have not been helped yet. I just came online and saw your question

The ECM(engine control module) is slightly different in connector pinouts between the 2, so you do need to replace the ECM with one from a 2001 2.5L and it will need some programming as your antitheft also goes thru it and if the VIN number programmed into the ECM doesnt match, it wont work. So this needs to be programmed into it with scan tool
