I know I'm going to get a lot of flack for this and negative remarks, but I need to know this before I proceed further. I have a 99 Legacy with a good EJ22 and manual tranny and a 99 OBW that originally came with a EJ25 and an Auto tranny. The OBW has had it's engine/tranny pulled already before I acquired it. My intention is to drop the parts from my EJ22 car into the OBW to get it driveable so I can move it to my new house. Everything from the old car has been pulled and ready to install in the new car except for the harness that goes to the ECU. Can I plug my EJ22 ECU into where the EJ25 ECU is or do I have to pull that harness? I'd like to know before I go putting everything into it and find I need to reverse some of the steps. Thanks in advance.

PS: To the naysayers, I got an unbelievable deal on the OBW and I already know the swap is less than ideal, but I need to roll with it.
