I'm adding a third function to my 2021 Mahindra 2638 for a grapple. Sitting on the tractor on the right below the floor board is the front end loader control valve. From my research, I'm supposed to connect the pressure side of the 3rd function valve to the "power beyond port or line". Does anyone have pictures that show where to hook up the pressure line? And the other line is supposed to go to a "return or tank line". I think I know where that goes but need confirmation. Please help!
