Meyer control 22695 for the V plows. This is used with 2 pumps - V68 and the V70. This has a 12 pin rectangle plug on the end of the harness. It also comes with a diode 15059 that must be used on the solenoid. Failure to use will burn out the control.
Start by using a test light on the 2 small pins on the solenoid.
1 should a ground and the other should be positive.
Usually they switch the positive, so the light will only light on up, left, or right.
I’m embarrassed to report that I finally found the directions for my controller. By holding down the on/off button, the controller turns ”bright”. All works as it should. They should have more pictures in directions
