SO passenger airbag light on, guess its a seat switch? or dirty connections. tried cleaning connecti

Passenger airbag light on not the usual SRS light , but the left hand baby carrier thing , and light is in with the airbag switched on or off . guess its a seat switch? or dirty connections. tried cleaning connections but still on so as i have just had a passenger in it after a long time of solo driving may be the switch showing load? how do these switches work? any info please, and yes battery disconnected for tests and er connections ! thanks for any help, MOT soon!

 

Update,, just been out for closer look and there is no seat pressure switch , I have deleted the connecter and made a proper termination , however the light is still on . this is the Passenger airbag light as this car has a switch to turn the airbag off if you have a baby seat there . switched switch on and off and passenger light still on them main SRS light is Out . any ideas, thanks in advance
