I can tell you about 567 which may be different.  On the upper set of solenoids, the extend and retract lines are closest to the DS  wall.  I made up a test jig to insert in the 2 pin weatherpack connectors with a indicator lamp.  By activating the generator slide switch, you can identify the solenoid.  This will get you close to the line.  Remember this system works at 3200psi, be very careful.  

I was at Bristol when the extend line gave up from rubbing on the strap holding the lines in place.  Had the slides out about 8” when it let go.  Had to identify the line set and isolate.  And, yes, they are 1/4” JIC. I now keep a set of caps and plugs!

Hope this helps.
