Mystery connection

[Sharpen]

Hello all, could someone help me identify what the green connector is in the pic below (its to the left of the clutch pedal):



Its not connected but everything seems to be working ok so i'm reluctant to reconnect it in case its like that for a reason.

-Also does anyone have a tip on how to remove the side light bulbs, looks light the whole front light cluster may need removing to get at them.

Many Thanks

Shane
