3-Point Hitch Bisson sub control / adding cylinder

[Catfish1500]

I bought a hydraulic top link for my 650g and plumbed it in to the sub control valve. Fired it up and to my surprise I it goes out but not in . Looking through the manual probly should of started ther lol. Looks like despite having two plugs only one is live. I see I have two ports under the seat are these supply and return? Dose any one know ware I can pipe in a different dual action valve?

If it is the same as my MT, you have to re-route your hydraulics to the ports under the seat to support auxiliary.

Ok that is the next plan then do you know if one is a return manual just lables one side as a test port
