Zetor 9540 hydraulics

[reljo86]

Somebody has messed up the hydraulic hoses and i want to know how they really should be connected.
I hope you can see the picture in the link.
1 Should be oil pressure in?
2 Should be oil pressure out to the rear hydraulic valves and if not eqipped then returned to the rear housing?
3 and 4 should be rear outer hydraulic circuit tapping
5 Hydraulic power lift cylinder? If the cylinder is removed then it should be closed?

Hope somebody can help
