What is this connecter loose under my central console?

[s3dave]

Been stripping out the old audio unit on the Sagaris, the unit included a number of modules (bluetooth, GPS nav unit etc), one of which was hidden under the centre consol. Just in front of the gearstick there is some car wiring, connectors and units, I also found a loose 4 pin connector- 3 greens and one grey (2 photos below), it does not seem to plug into anything. Can anybody help to identify this please.
