Wiring for factory fog light button

:
2015 Mazda 6
So i put aftermarket fogs on my MSP, I bought a OEM foglight switch from Mazmart, I just need to figure out which slot is power/ground and constant so I can plug it up, and take this generic button off...I have played with it a few times and tried to figure it out. But im tired of blowing fuses...lol, anyone know??
