Implement steering angle sensor via ADS1115

Hello everyone,
I am currently failing to connect the steering angle sensor to the arduino so that I can see the live steering angle in AgOpen.
Do I need to change/adjust anything in the Arduino program for this?
Here is a schematic of my setup (from Andreas Ortner)

Thank you very much for your help!

I strongly advise you not to use this diagram. It is obsolete. MMA and BNO55 are no longer supported and used. It is preferable to start with a more recent assembly. AIO4.5
