Pneumatic Plugging in

So there is different ports for the air to go in and out from the actuators and there is 3 in ports and which one do we put the tube into to go in. Also is there specific digital ports on the brain the the actuators need to be plugged into?

Question. Our teams have the double acting piston. Is the piston in the video single acting? Or is it just the solenoid that you are changing/adapting? Also, the screw that you used for the solenoid value doesn’t come with the kit. What size and length is it?
