In my 2018 Tesla 3 in the back of the center console (the cover has to be removed to access them) there are 2 blue connectors connected to each other where an OBD2 connector can be inserted between them. See attached picture. Are there any harnesses like this that have the capability of adding wire connectors for other aftermarked devices, e.g. a dashboard instrument cluster display unit, and others at the same time? Alternatively, how can such a device be modified to attach more devices?
