Secondary Air Injection
IIRC there are 5(8mm) bolts, 2 on the bottom, one through the side where the fuse are located and two more up by the steering column (you will have to remove the plastic between the steering wheel & cluster to expose those).

IGNORE THE CIRCLED AREA!
The two 8mm bolts I'm referring to, are to the left and right of the steering wheel on the lower portion of the bottom photo.
