In this pic, the bottom left corner should be the cutout where the obdII port comes through. So that would be towards your right if you were sitting in the driver seat. The back has those 2 fingers that hook over whatever plastic stuff is back there by the firewall and the push clips go in the front. Oh and looking at it in the pic, the piece is upside down. The side facing the ground should point towards the roof and the side we see should go towards the carpet.
