What are these wires??

Hi guys,

I've just been routing around my engine bay looking for the TCV etc and came across these?

Any ideas? They are to the left of the bay, above the washer fluid reservoir etc...

i think thats the level sensor for the expansion tank,they should be connected,
if they are unplugged im guessing the previous owner disconnected it to put the light out...as the sensor in the tank can faulter

follow them back,does one plug go to the resovoir
