OTRATTW wiring help

Wiring my led bar into my otrarrw switch finally but cant find the pinout diagram to my switch. I know black wire is ground, white is power in to switch, blue is power out to light. but im not sure which pin they go into on the switch. Did a quick google search and cant find what i need. Heres what im looking at.


Thanks for the help guys
