I know the picture sucks,,,,it kind of hard to get your I-phone between the passengers seat,,,,this is a bad picture of the seat position sensor on a F30,,,,passengers airbag light was on,,,,I had faults for the passengers seat position sensor and passengers seatbelt buckle. Here you can see the seat position sensor is on the seat rail,,,it slides along with the seat,,,you can also see the seatbelt buckle,,,,so we decided to replace both. This is the main seat connector,,,this is a common seat connector,,,,you remove the differt colored connector from the big yellow connector.
