Add a hydraulic valve to Kubota Bx2350

[Davey Wayne]

I have a Kubota BX2350 with no front loader valve and want to install a hydraulic top link and one valve .I would like to come off the ports where the loader valve would connect .I can make my own hydraulic hoses and want to do this as inexpensive as possible this will only be used to operate the top link.But here is where I get confused there is a power, power beyond and a return port on the tractor side. Anybody know how I can configure this and a suggestion on a valve?THANKS
