Cannot identify parts

I have a 1987 911 carrera that will not run because of a broken electrical connection, but I cant identify the part using the parts catalog or the service manual. Directly opposite the ignition coil toward the left side of the engine is a bracket (the bracket is mounted on the engine) that supports 3 electrical connectors, two are black and one is off-white. The off white connector is broken and the engine will not run. I need to repair this but I cannot find the part or support bracket in the parts manual. Can anyone help me in identifying the parts?

The car is in the shop so I cannot get a photo and the mechanic and I disagree on what the part is. I went through the service manual again and I think I have found the part. It looks like the temperature head sensor. I had the car running after it quit and I then unplugged the sensor and engine stopped immediately. When I plug in sensor again th car will restart. On numerous occasions the car abruptly quits and will restart randomly. The plug is actually cracked on the engine side.

Yes that is the part. Thank you.. Apparently this part has caused trouble as it has only 1 wire. There is a modified part that had its own ground wire. Thanks again

Are you sure its the head sensor? I ask because the car will run with it dissconnected, but poorly if the engine is cold. The engine will not run if one of the other two are disconnected. Those are the speed and crank position sensors. Both located in the same general area but further up on the engine between the transmission.
