Mystery Wire

[ChaosSaint]

So yesterday was the first time that I changed the oil since I got my brand-old Pathy; it turned out looking like a crime scene - luckily, the rust and caked on mud soaked up some of the oil... what a horrible design. Anyway, just before I put the new filter in I noticed a "mystery wire" - with the connector a little mashed - hanging out the the harness below the oil filter and next to the starter. The gauge of the wire seems too small to connect to the starter, and everything seems secured to it; any ideas to what it connects to? an o2 sensor? My trip odometer stopped working, could it be related to that? The area is pretty cramped and it was getting dark out so I figured I would just ask, hoping someone here would know what it connects to.

 

 

Any suggestions would be awesome...

That looks like the oil pressure sending unit wire. As far as i remember that sensor will not send an error if unplugged so you wont see anything wrong on the ECU if you pull codes and it wont show on the dash. The oil pressure sending unit should be right beside the oil filter or at least very near. it looks like this

Hope that helps

Jack up the passenger side front tire and you can see where it connects through the wheel well.

If the sender is unplugged, the oil pressure idiot light will be on.

You guys are on point!
