Need to know which BCM is correct

Hello I need to know what is the right bcm to have in a 2010 2L Petrol Mazda5 (CW) as I think the one I have in mine is the wrong one. For those who don't know where the BCM is located, it is behind the glove box.
 
Why you think you have wrong BCM?
Why it's been changed in a first place?

My point in this is, that it's codable module, so it can be correct but still have wrong accessories coded, if changed from a another car..
