Tacoma with seat code errors

I picked up a 2005 2nd gen X-runner for around town use the other day. I pulled the codes and found some I am unfamiliar with. Thought someone may be able to give me some incite.
codes are:
B1653 Drivers side seat position sensor
B1655 Seat belt buckle switch (drivers side)
B1660 Passenger seat airbag active mode indicator
I have pulled the seats and all connectors are plugged in, but under the drivers seat there are two loose plugs under the carpet. See pic. I might mention the seat belt light comes on on the dash, but no warning sound and it goes off when the belt is plugged in.
Does anyone know what these go to, or maybe if something has been removed that is causing these codes?
Any help would be appreciated.
