This sensor is also on the 86 diesel ranger I am working on. It is located behind the injection pump on the head. The braided hose in the picture is the return feed to pump and grey fat wire is glow bus bar wire. The sensor has two male prongs that connect to a female connector in the wiring loom for the injection pump and glow plugs. Cannot find reference to it anywhere! Ford manual does not have it, and the mighty max's I have worked on in the past do not have it. The motor I am working on had the sensor broken when re installing the motor.
