This is some very cool functionality. I may have to get one of those devices.
Instead of using the OBD port, where can you tie into the CAN bus? I tihnk I remember someone menstioning that there is access in one of the trunk wiring harnesses.
You can use any point of the defined can bus. They are 3 and on GitHub I associated each function to a bus.
you need the wiring diagram of the car to define where you prefer to install it. Can bus is almost everywhere in Giulia
