Hi @Seelsy
For a SP10-57 valve I would say the way @darrenjlobb have installed his valve is the way to go.
If you are using the tractor’s power behond you should install a pressure compensator. Else the valve will move way too fast if something else is looking for pressure.
To cut autosteer I now have this pressure transducer on the orbitrol LS line. I had to modify a little the arduino code but work really good.
