You've likely found your solution by now. But I had a similar issue and needed to find the pin layout for this board. It's here

And in pins.h it's listed under "Ultimaker" as you can see from the:

Introduction
The Geeetech GT2560 is an Ultimaker derived board. It is a single-board design, which has an integrated ATMega2560 16Mhz processor.

Can confirm, I was looking for the Heated Bed Pin and it's indeed on PIN 4 and the Ultimaker profile is the only one there with that.
