It's above and to the left of your left knee. If it was a snake it would have bit you every time you got into the car.
Thanks for explaining--I'll be coding for sure then. As for what I meant when I didn't have time to find my OBD unit, I meant the actual wifi OBD unit I purchased online to do the coding via app; sometimes being too organized works against you and you actually have a harder time finding where you kept things.
