ym240 3 point problem

[josephmitchel2003]

I just got a ym240 and the 3 point is not working at all. The 3 point just sits there with no power at all, you can lift it up and down by hand. The guy i bought it from told me I needed to hook up high pressure to a port on the back which I now know is just the bleeder valve. does anyone have any pictures of how this should be routed. Any help would be great.
