If it's got a bulb on the end, then the "wire" is probably a capillary tube. If so, I'd be leery of clamping the hose over it. But it sounds like it worked for ZugyNA.
Yes...small tube...don't kink it. Use some gasket goop where it goes under the hose...have installed this on 2 vehicles....works very well put in the upper hose with the bulb pointed towards the radiator in line will the coolant flow.
Leading the perpetually ignorant and uninformed into the light of scientific knowledge. Did I really say that?
a new policy....I intend to ignore the nescient...a waste of time and energy.
