Coolant Temp Sensor and Mystery Vac Hose?

[CREGAN]

Hey guys- quick question for you. I am changing my glow plugs and doing some general mainenance and I am trying to locate the coolant temp sensor. Which one is it?:

I also have moved the intercooler out of the way to work on these bits and bobs and I have a mystery hose that doesn't seem to have an end. Can someone identify this hose?:

Could try disconnecting and.or shorting them when the beast is running and see which one lights up the dash indicator.

OK, Thanks to the boys overseas I have solved the coolant temp sensor question:

Now just to identify that vac hose. Wonder what it is for and if it is supposed to be disconnected?

Do you have an EGR?

No, I blanked it off. I used the adapter for that vac hose and it is still there. When I was moving the intercoler out of the way I heard something drop onto the bash pans below. When I took them off to change the oil I found a little cap with a mitsubishi logo. It fit and I think with my powers of deductive reasoning and my super detective skills, I would say probelm solved. I have been wrong before. Several times in fact.
