E12 518 Wiring/Plug Identification

[warrenk]

On the bottom radiator hose of the E12 518 there's a sender unit with two wires on it, does anyone know what that is for?
The wires are not connected as the lugs broke off,
I will see to that before the car hits the road again.

Take a picture. The only sender on a radiator hose would be water temp, but it has that already on the coolant neck on the head.

Here's the photo of the sensor I was asking about.
According to RealOEM, Aircon car's had a different bottom hose?
