Psu type 2

Omteck k40 I managed to downgrade the panel to a pot and meter but can’t find a wiring diagram for the type 2 psu. I need the laser switch wiring. I got the board wired and working but no laser. I’m sure it is still simple like a ground missing. Does anyone have a simple wiring diagram showing switch setup?
