I found 3 black/blue wires behind the fuse box and anyone of them change when any doors open/close !? Does anyone can tell me where to find the right door trigger wire !?

Thanks

 

Thanks ...
by the way, one my first post, what i meant is that any of the wires that I found was changing ... no change at all when the doors open/close ! I know one of them are supposed to change from 12V to GROUND when one of the door open but I can't find the right one !

The only option that I'm seeing right know is to take the black/blue wire behind the cluster. I know it is there ! Also, it must be coming from the bottom, but where ?

 

You can also tap directly into the dome light wire running up the driver's side "A" pillar. Funny thing about the Mazdas, all the doors are tied together, i.e. the key-in buzzer sounds when any of the doors are opened.
