The sensor I am talking about should be on all tpi motors but atleast the 350. It is located under neath the winshield wiper motor under the hood(driver side). The wire and sensor are about 3-4in long. Is it part of the long wires and in these wires are the tops of the fuel injectors. But like I said it is underneather the winshield wiper motor and sorta looks like a small straw that is a spherical shape. Does anyone know where it plugs into?? I can't figure it out

 

sounds like your o2 sensor connector, the o2 sensor is in your exhaust just below your steering column.

hope this helps
