IXEG 737 data ref issue

[TxPanda]

Hello, I am trying to make a home cockpit for the IXEG 737 but I need the datarefs to do so. I can find many in the documentation PDF but I don't necessarily know what they do in the sim. I am trying to use a tool called the "Datareftool" that can show what datarefs are being executed when a switch is pushed and it can also show me the ON, Off values which I need and also the step value such as "each position of a rotary switch increases the value by 2" please tell me where I can find these datarefs and values. Thanks
