Pinout for SD-AD112

I have a SD-AD112 405nm diode that I am going to fit into a Jayrob pocket mini build.  I realized that I am not sure of the pinout for the diode.  Can anyone point me in the right direction so I don't fry the diode?  I reckon the penalty for incorrect polarity is death...of the diode!

try this, i'm not sure but it is probably this
