hydraulic schematic for ih 784 with 2250 loader

[rmthurman]

i recently bought a 784 ih and a 2250 loader(seperately). the tractors hydraulics had been re-plumbed with some sort of a return loop for a wood-spliter (?). several lines are hanging loose and un-pluged. i was wondering if any one knows where i could find a good schematic to help me get it straight. tia.
