  If you need 5V ttl signal to enable it any output pin will give a 5v signal.  But only 1 pin gets controlled. Other pins might be gnd/12V? That is at least how my laser works.

  At least same pins as for me. I have added 12V to fan so I can enable laser by enabling fan. PWM pin goes to a free pin. When I enable 12V I see a weak light I can use for optimizing focus. When I enable pwm as well I do not want to be in same room for safety. That is the pin number you need to enable the laser.
