I am trying Attaching a bobcat dozer 80 to a Terex skidsteer

Does any know how I would attach a terex pt-60 skidsteer to a bobcat dozer 80. I am trying to hook the solenoid direct to the electrical connector on the Terex. I can get it to move one way and not the other. the valves are stacked so I assumed that activating one solenoid would extend the cylinder and activating both would retract the cyclinder. But it doesn't retract.



The terex skidsteer has an electrical output of 12vdc coming from the left joystick with 4 buttons, so I have 4 12vdc outputs.



Does anyone have the hydraulic schematic or a manual on the bobcat dozer 80 ?



Also the dozer had a control board on it that I intend to bypass, maybe this is not even possible.



Any help would be great



Thanks
