Hey, I just got the NOS remote bottle opener used and it has no instructions and only some hardware with it. I need to know which wires the Red Black and White go to. I know the white is ground, but thats it. Also, on the actual opener, there are two holes, one says A and the other says P. I'm assuming on is inlet and one is outlet but which go to where? And how the heck do they screw on the lines and bottle? I'm guessing I"m missing some fittings...but which ones? Tia!
