The basics - there are two rather large torx head bolts at the rear of the seat track (one on each side). Remove these, lift the rear of the seat a bit, then pull up as you slide it back about 1".
If you have manual seats (no power or heat) there is only one plug, under the driver's seat, for the seat belt reminder. Of course you have to disconnect this plug before removign the seat (duh). If you have power and heat, there are more plugs under there that have to be disconnected.
