This was hanging back behind my 86 5.7 350. I have been feeling around for a sensor port, and searching the part number I have nothing. Maybe it used to work with the AIR system or a vacuum pump I don’t know. The yellow and brown wire does not help me. It is tapped to the green wire that I believe is the coolant sensor.
