Srs module differences?

[heliosGT]

HI!!! Does anyone know the differences between BCP8 57K30 and BFD2 57K30 SRS' modules?

MAZDA 3 2010 > BCP8 57K30
MAZDA 3 2012 SKYACTIVE > BFD2 57K30

Does the BCP8 SRS MODULE work on a MAZDA 2012 Touring SKYactive?

Thanks for your help.

I'm from Guatemala and it is very difficult to find this parts in this country.
