I'm looking for kind of a generic answer here, not really dealing with any specifics.
Most autosteer valves from Trimble, AgLeader, Raven, etc are just a D03 or D05 proportional valve with a 12v coil for left and a 12v coil for right. Some also have a 12v coil (or two) for enable.
If you have a valve of this type, is it possible to use the valve between Trimble/AgLeader/Raven/Etc just by switching the plugs around?
