New holland canbus

It’s a 2021 T7 autosteer ready.


Yup thats the green canbus plug.
You can either connect there or to the 40 pin connector behind the passenger seat. Pins h and j from memory
You will need to access the h menu to turn the autosteer valve on.
Depending if its had autosteer on it before or not, if not you will also need to do a WAS and SPOOL calibration which then calibrates then sensors and the steer valve and hope its all working and you get no error codes

Yes, how can I “open” the calibration? The tractor has a screen but it has never has any autosteer. And another question is which program should I flash in teensy from configomatic

Thanks

You’ll need the calibration plug to access the h menu, its all done through the dash screen. You will also need to do a valve calibration if its not had autosteer on before.
For the teensy firmware i use it from the boards repo, its the aio v5 canbius modified sketch and i use arduino ide to flash it
Youll need to go into serial monitor and select brand 2 for nh and also select P for panda gps.
Have you looked here.
The calibration procedure is also there i think. The WAS and SPOOL calibration can be a bugger to get started
