curious. that was always something I wondered. I have hydraulic steering and autopilot and there it is simple - if steering does not move the ram - autopilot pump does. I had trouble simulating the separate ram behavior (I connected one side to the other - but could not get it to move freely).
Anyway, I see the point and it looks like a nice all in one setup.
