I agree with the others about not connecting port-to-port on the manifold.
You need to deadend each unused port using, either a plug you can purchase, or juryrig a simple plug like the attached.
Other than that the tubing seems to be correct for your one cylinder.
The supplied pressure of 35psi is good to activate the solenoids.
Try swapping the two end hoses of the cylinder to see if the activated side is being affected by those flow controls.
Test using the manual blue button to make sure the plumbing is right, but then look back at the electrical connections.
- Make sure the solenoid you expect (the second from the bottom or right in your photo) is wired to the correct PCM output. (The wires cross behind the regulator with another pair so they can't be traced from your photo)
- Are both the light on the solenoid itself and the LED below the PCM solenoid connection changing when you attempt to switch cylinder direction?
The photo doesn't show the back of the regulator well, so look for the flow arrow on the regulator and make sure your high-pressure line is going in the port directly opposite the flow arrow (on the side of the tail end of the arrow).
The regulator has one input high-pressure port and three regulated low-pressure output ports and all can be used.
We use one of the output ports for the low-side pressure gauge and the other two low-side outputs can be used or plugged as desired to direct the low-pressure outputs.
