what your gunna do is have a fill valve and dump valve running to the bottom port of the cylinders and then just wire up your valves to the switches, and to have the wheel suck up your gunna want to let the air out of the top of the cylinder and fill the bottom of the cylinder.
hey man you should have the outlet on the top of your can. that is your fill/dump. the port on the side of the can is for your dogleg. you really need to use the old block style vales for the quickest and easiest use.
