I have a 95 dodge stratus with the 2.5 liter and i need to replace the ECU and i found a junk yard that has a lot of them and was just wonderin if anyone knows what i need to match up to swap this out. does it have to be from the same year or just the same motor and i was told that i have to match the numbers on the ecu itself but when i went to look at the ones at the junkyard they had like 15 and all of them had diffrent numbers. can anyone help me out
