I still can’t seem to read any data from the car. I tapped directly into the yellow black/brown pair of wires on one of the connectors behind the glovebox, and the pi seems to understand it’s connected to some kind of can bus interface, but it is not receiving any messages. Does this have to do with the rate at which the vehicle transmits them, or am I just doing something wrong?
