Step 1:  Disassemble

Step 2:  Probe or look at the board to determine which trace carries the trigger signal and where you can pull the proper voltage from.

Step 3:  Use the 555 timer method ( (I know that it's for a mouse, but you can use it for this just as well).  If you have access to an oscilloscope and can find the pwm line you could use a wire to that instead of the 555 timer method.

If you are still confused, I wouldn't recommend that you try to do this.
