So first of all big Thanks to @CommonRail for helping me out 
I managed to get a Deutz with pre installed Danfoss Valve to work with agopengps.
This Deutz has a connector under the right console where all Can Bus are accessible, makes it easier to find the right one. The bus is for steering etc is called AutoG.
We got it working after a while, but the main Problem that we had, we weren’t driving so the Tractor would not steer 
The next step is buying RTK Receivers and build the full system.
