Adding controls to run 3 pt hitch attacment from backhoe rear

[Solidoak]

So I would like to add a 3 pt hitch to a case backhoe. The backhoe is originally removable (with controls) and there are two hoses that feed the hydraulics which use large quick-connects. There is about 6 cylinders that run the hoe (3 that can run constantly for your basic dig functions). I would like to install a common 3 pt hitch that will have 2 cylinders (2 spool valve)... What would be the correct way to plumb into this system? What type of valves and reduction would need to be done to make this function well?
