SRS related connectors are RED and as far as I remember there is only a 2-pin red connector under the (European) seat...was the connector you were looking at RED (SRS related) or BLACK (possible power seat or seat heating related)?

SRS related problems (light stays on) always need to be reset after the cause has been repaired.
