Megatronics with RepRapDiscount Full Graphic Smart Controller

I would like to connect a RepRapDiscount Full Graphic Smart Controller to Megatronics v.2.0 but I'm missing some pinout information. Where I can find the information how to connect the screen?
Does anyone already connect the lcd screen to the Megatronics and figured out how the pins should be connected?

I've uncommented following line and firmware should be ok.
#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
