What is this wire

Hi, I have looked through the circuit diagrams and searched the web but I can't find what this Blue with black trace wire is.
The insulation had become brittle and the wires broke off. So I stripped them back until the insulation was ok.
The car is a 1990 Galant VR4 Aussie spec.
The loom has the coolant sensor wires and o2 wires. Thanks.

It goes to #4 in this diagram

It is a thermoswitch used by the climate control computer to turn off the a/c compressor and turn on the fans when the coolant temp gets too hot while operating the a/c
 

Thanks, I can just see the sensor behind the hoses in my photos /ubbthreads/images/graemlins/blush.gif
