Engine Coolant Sensor Location on 2004 Mercedes-Benz C230

My check engine light came on, so I went to the local auto parts store that put their computer on it and found that it was the Engine Coolant Sensor giving an error. I drained the radiator and added new coolant. I ordered the Engine Coolant Sensor online and I can't seem to locate it on the car. I read that it was attached to the overflow container, but the only thing I can see attached to it with wiring is a 6 inch by 2 inch cylinder. That does not look like the part I received. Does anyone know, exactly, where the ECS is located?
