Im having a hard time getting the following cellular module

to work with the Mega IO Expansion Shield V2.4, and a MEGA2560.
Sky wire has an Arduino shield and a couple example programs here:

I am using the SMS example, but cant seem to figure out what pins I should be using in my code.
I am using the XBEE2 slot on the expansion board (I belive its serial1). I dont know what pins to put in my program to control pin 20, 16, and 9 of the XBEE slot. Does the expansion board even connect all those pins, or are some not connected to anything?
