Hello,

If the original tags are on the pilot lines under the cab, you can swap the lines by using ID tags on the lines.

R1=ORANGE--BOOM UP **4I-9525
R3=GREEN--BOOM DOWN **4I-9527
L3=BLUE--STICK IN **4I-9523
L1=RED--STICK OUT **4I-9521

Switch RED L1 STICK OUT with GREEN R3 BOOM DOWN
Switch BLUE L3 STICK IN with ORANGE R1 BOOM UP

This is only for the bulkhead plate under the cab. Turn the machine and remove the second from the front bottom guard and you will see all the lines connected to the union bulkhead fittings. This is the point where the valve lines meet the joystick lines. Tag the lines yourself to remember which one you moved.
