There is a difference but i have a playchoice gun in my vs hogan and it works supposidely vs has 2 plugs 3 wires on each and playchoice has 2 plugs 3 wire and 2 wire with a looped wire
there are similarities- the brown wire will be the 5v, the blue is your hit detection, purple is your trigger and green if you have it is the ground. at least thats how it worked for my zapper
