I have the box on mine, you may have to take off your grip to see the board if its like mine. There is a light on the board,you should have 1 sensor wire that is longer then the other thats the one that goes to the front of the ram(nearest front block) hope that helps.
I have the box one and I also have the TT and there is no light on the TT for questions on how to set the TT ram sensors Rich at www.sandridgepaintball.com sells a video that will explain any question you could have about the TT and and box one
There is a light on the board thats how you time the gun
there are 4 prongs on the board you need a jumper on 2 of the prongs. If you dont have the jumper you CANT TIME THE GUN or
You will NOT be able to put it to unlimited fire either.
