Rear Water Temperature Sensor - Wiring ?

I've a car here with a smashed connector that goes onto the 'Rear Water Temperature Sensor' at the firewall.
This thing

Does anyone know which way the wires go onto the sensor ?
There is a black wire with a green stripe and also a blue wire with a white stripe.
Or does anyone know where I could get another connector ASAP ?
