The 2 clamps go left and right on the front corners of the tray. The 2 hooks are screwed in the back of the tray, on each side of the steering column. You can now secure the tray on the back with the o-ring around the steering column and hooked into the hooks.
Now position the front of the tray as you wish and secure it to the body with the clamps and the screws.
