How to configure extension board steppers on RADDS

Hi. I am building a large format printer with 3 stepper motors controlling the bed height (Z axis) and 2 extruders.
I am using RADDS with the extension board.
I need to know which two stepper drivers I should attach the additional two Z stepper motors to (physically which pins) and how to setup the firmware so the 3 motors are controlled correctly. In the schematic, there are a variety of pin numbers for the extension board. Does one of those numbers correspond to the pins definitions? Is there already a label in the firmware for the two extra drivers? I guess I'm trying to determine which set of drivers pins is which...

Some help with this would be most appreciated!
Thank you,
Bryan

    Anyone?

    I think the motors on extension board are already configured as ext3 and ext4. Only thing I'm unsure is if this is for 2 or 3 stepper driver extension board. But I think it is for 2 extruder extension board.

    What determines which is which? Is it one of the pin numbers assigned to drive a given stepper controller? Is the number the same as the ones in the pins.h in the firmware?

    If you use config tool just select the socket. It will us ethe pin description from pins.h in 402 section whcih is radds. Ext0-2 are on board so 3-5 are for extension boards.
