1994 LeSabre Temperature Cooling Sensor Location???

Hello,
I cannot seem to find the Temperature Cooling Sensor location on my 1994 Buick Lesabre with a 3800.

I have found the Temperature Sending unit that is behind the throttle body on the intake. That has one wire, and if I take of the connector then the Temp Gauge does not work. So I figured that has to be the sending unit.

I am looking for the two wire Temperature Cooling Sensor that runs the fans for the radiator as the fans do not work.

Any help would be greatly appreciated.
Thanks
Mike

According to the service manual, it's right in the same area. Looks like the wiring runs in the same loom. I looked on my car, and it wasn't readily visible (btw I don't have a temp gauge, so I'm assuming I don't have a sending unit for the gauge).
