A bit difficult to describe, but under the seat there is a black plastic sliding tray affair, I think held in with a peg - once slid forward the cover will hinge down giving you access to the plug and socket. As it is for the airbag set-up most people will recommend that you dis-connect the battery for at least 15 minutes before trying to undo the wiring. You may find it easier to get at the wiring etc when you've unbolted the seat.
Not sure about the rear seat-belt issue - I think if the car is classified as a 5-seater it needs the 5 seat-belts. Are you sure it isn't just tucked under the back seat squab.....if it isn't, you'll find one from a breaker easily enough.
