306 Airbag lamp is on

I've called Peugoet, and they said thay had to solder a wire under the seat.
I'v read that the "connector under the seat needs cutting
off and resoldering."
Which connector?
I have 3 male and 3 female connectors under my seat?

Going off the advice that i have recieved for the same problem i would
think it is all of them.

 

Thanks, I'll let you know of the result.
