YJ steering box Q

does anyone know which port on the steering box is the pressure port and which one is the return port? im swaping one in my XJ and the ports are in different spots then the XJ box. I know the fittings on the hoses are different sizes and will only fit into one of the ports i am just not sure if the YJ used different lines or if they just switched sides on the box

OK I got it the XJ lines will only go into the YJ box one way and its the right way. the XJs pressure and return ports (on the gear) are opposite of the YJ ports. just a FYI is anyone was wondering
