What is this sensor?
The sensor in the middle of the picture with the yellow casing had two wires that were independant of the wiring loom, so I'm assuming it is a sensor of some sort that ran through to the dash.
However I have no idea what it is.

If there's commotion coming from the passenger seat, and nothing but earth going round and round outside the windows,.......then everything is not as it seems!
