*** all connection use the laser connector ***

12V AC/DC is the power input, and connects to the + and - pins on the laser connector.

TTL is the TTL/PWM signal, one pin connects to the S pin on the laser connector (you may need to connect the other to the - pin which is actually a ground but usually not required)

12V is the laser connector (goes to the laser diode), and I am not sure but GRN is probably the fan.
