What's this Cable/Cord for ??

So it's connected to the radiator at the bottom corner but it's not connected to anything !!

Do you guys know where it's meant to be connected too ?? Here's some photos 

My car is a R34 GTT,

A/c thermo fan, turns fan on when set temperature is reached.

It's for a temp sensor.  I fact, you can see the temp sensor in teh rad tank in the 2nd pic.  Don't worry about it.

I also believe it is for Thermo fan. Perhaps previously the car had after market thermo-fan and that's what was left in your vehicle after removal

No, it's the over over temperature switch that is used to run the AC fan when EVERYTHING is too hot.

And when I said 2nd pic in my above post, I meant 3rd pic.
