NEW RTV 1100 WITH ELECTRICAL PROBLEM ON OLD CURTIS PLOW

I traded my 2016 1100 in for new 2020 1100 and had the dealer install everything for a Curtis plow except the blade. Mounted my old plow yesterday and it didn't work. I am not receiving power to the hyd. motor. I rung the Red cable from the motor to just before the trailer type plug. I really don't want to open up the plug to see if the continuiity is there from the motor to the front of the plug. I cannot find a diagram that tells me which pin is the correct one for the motor.

Can anybody...
