An apparatus includes a processor and a plurality of on-board diagnostic (OBD) interfaces, in communication with the processor. The exemplary apparatus also includes a configurable housing, adapted to flexibly present an orientation of an OBD interface. The apparatus further includes persistent and non-persistent memory, in communication with the processor and a non-OBD I/O interface, in communication with the processor. The processor is configured to detect external device communication through a first OBD interface and function as a pass-through to a second OBD interface.
