Ok well won't let the picture post but if I'm standing in front of the engine it's on the left back corner on the bottom

That would be your right rear sensor. If you're sitting in the car it's the one on the right, correct? Furthest sensor back? There are two per side. One at manifold, one after cat. This isn't rocket science
