warning lights airbag and abs 1.2 Clio 2004

Over the years the light for the airbag has come on and wiggling the wires under the passenger seat has made it go out. The abs light has never been on before but as they came on together I think the 2 are related to those wires and connectors under the seat. Wiggling won't make them go out this time. Has anyone had this problem? When it stops raining I'll have a proper look at it but any input for a similar fault would be welcome.
