I understand that, but if I'm not mistaken, I would only need the bus to power my obd2 device, not to 'talk' to it necessarily.
In that scenario, would a 9 pin to obd2 adaptor work? I guess I could always get one and try and if not return it...just curious if anyone had my particular situation before.
