Exhaust in Solenoids

I think I've figured out everything up to the pressure regulator. It looks like the output of the regulator is split, with one going to the manifold, another going underneath. Where does that connect?

Trying to work out the black tubing connected to the manifold outputs. I cannot tell if the two inputs to the cylinder are coming from corresponding A/B ports, or adjacent sets of ports.
In any case it appears that you have plumbed the three unused A ports together, and the three unused B ports together. If all three (or four) of the solenoids are in the same position, this shouldn't be a leak, but if any of them is different from the others, you will be in an exhaust condition - pressurized air coming in one branch of the T and right out through another.
If the cylinder is plumbed to different solenoid valves, The only way you can operate it in this setup without dumping air is to switch all four ports at the same time.

The real solution to this problem (more manifold positions than you have separate items to control) is to plug the holes individually (we have some plugs in our shop, but don't know whence they came) or to use a "Blank Station Kit" like Vex's 217-2949 for each unused control. Edit: I see it is also called a blank station kit with the same part number on the WCP link you provided.

Edit2: Found the plugs like we have on MSC.
