You only have 1 set of normal outlets then.
Bet there is a round contorl knob, or something to pull out, to 'phase' the load monitor cylinder with the 3-point. You might not want to mess with that knob, it is possible to hurt things if you pull it at the wrong time. (According to the manual of my 7700 anyhow.)
The load monitor works mostly with 2-point (semi-mount) plows. Without using it, you set the front of the plow with the 3-point lever, and the back of the plow with the hyd lever.
With the special cylinder, you can set up the load monitor to operate the plow with only the 3-point lever. It will delay, & drop the rear cylinder when you drop the front of the plow, and again at the other end it will dely, then raise the rear of the plow when you pull up the 3-point lever.
Aslo, if you slightly raise or lower the 3-point lever, it will also slightly raise or lower the rear of the plow, keeping it level. (This part works better with some plows than others.)
I'm sure the idea works with other stuff, but a semi-mounted plow is the only thing it was used for around here.
