    my issue is it will not go into gear on its own by the shifter (forward or reverse) i ran a jumper wire between two plug ins on circut board and have movment now but only in high gear (2 speed) need low gear working....anyone have any insight?
    also the quick attach hydro system isnot working...

    Are you getting power down to the A/B valve at the coupler? When you switch are you pulling the second joystick to give hydraulic power to the cylinder?
