On the nitrous plumbing A1A I have some pictures of my setup.. .

Perhaps I’m confused. You seem to have the correct lines, but not connected to the right ports.
Simply turn around the bottom plate. Hook the blue lines to the blue fittings and the same for the red fittings.
The “Tee” fittings look like the have 1/8” NPT threads that will go into your solenoids....
Use what you got...
