Hi Folks
I have an eaton vickers valve like this one MCD-8632 EATON - VICKERS For Sale in Fort Dodge, Iowa | shop.thegatorcenter.com The solenoids (the two brass looking nuts are on top of these) are just isolation for when autosteer is not in use. I am using a nano board, MD13S cytron board to drive the motors, an ADS1115 analog digital convertor from the wheel angle sensor, and a single channel relay to control power to the solenoids. From the nano the signal to open the solenoids comes from D9 to the relay which is wired normal open and closes when the autosteer switch is pulsed. The cytron is driven from D3 to PWM and D4 to DIR it has 12 volt power input and an output to each motor (the black box type on the right and left side of the hydraulic valve) The solenoids and these motors each have a ground as well. Mine grounds are all wired back to the box into a common ground from the tractor battery. I tried to attach a sketch of the wiring hopefully it comes through.
Good luck
