thinkcentre m91p temp sensor pinout

I have the 2N3904 transistor, that used as thermal sensor.

Genuine-Lenovo-ThinkCentre-M91P-M73-Temperature-Sensor-Cable-SFF-54Y9922 Genuine-Lenovo-ThinkCentre-...

Can somebody give me a pinout of the thermal sensor connector for properly wiring this transistor to the connector?

I'm confused, the photo in the link above shows it having a connector.  Isn't a case of simply connecting it to where the old one was?

Thermal sensor was missing in my case.
I have just a piece of wire with no transistor on the end. I get it in this condition from the previous user.

Disconnect this piece of wire and connect the new sensor.

If nobody will help me with pinout, i guess i`l do like you say.
The case is that in Ukraine price of new sensor plus shipping is greater than price of brand new compatible motherboard.
