I'm replacing my battery cable assembly and I came across this extra wire floating here. It looks exactly like a fuel injector wire, it even connects to my fuel injector but only reaches the first 2 front injectors near the battery. I couldn't imagine ford giving an extra fuel injector cord would they? Can anyone tell me if its extra or actually should be plugged into somewhere??? I hope i didnt pull it out on accident when taking my battery off.

Its hard to figure out what side of the engine you're on based on those pictures, but that definitely goes somewhere! Can you post pictures of a wider view so I can see where you're working at?

Yup just like RedDaemon said. Its connected to the main harness thats near the drivers side heads. As you can see that small wire connects to the bigger wire set thats right next to the battery (near positive battery wire)

Could someone take a look at there car and see where its connected and take a photo?? Thanks in advance for your help guys.

Here is another photo. That wire is connected to the wires in that red circle. Also its not the cam sensor wire since I already have one plugged in there. Plus this wire has the same connector as the fuel injectors.

De-gas bottle low coolant warning sensor. The plastic push pin goes on the side of the battery box.

wmburns, thanks!

Thats exactly what it was too! . I also plugged it in and now my coolant light wont go off! Duh!!! I guess the previous owner left it off because the gauge that reads coolant is bad lol. I see why he didnt replace it though, the stupid sensor is built into the reservoir. So you pretty much have to buy a new reservoir in order to get the gauge to work correctly. Talk about ford making $$ on that one. I just unplugged it lol and I'm happy. I always look at my coolant level every time i pop my hood anyways which is like 2-4 times a month.

The sensor can be triggering because the coolant mix isn't in the acceptable range for the computer, or the previous owner could have gotten it wet by cleaning the engine and just hasn't let it dry out.

The system consists of a magnet float and a sensor that activates when the float is at the bottom.

I have found two reasons the coolant level sensor fails.

The sensor gets dirty from scale and other grime and then sticks to the bottom. Sometimes cleaning the de-gas tank will free it up. However, the tank is difficult to clean because of all of the internal baffles.

What has given me limited sucess is to remove the de-gas bottle and soak in a vineager solution. Shaking and letting it soak. Repeat. Repeat.

The other cause is a water logged float. IE, coolant gets inside the float and it becomes too heavy to float. Note, the float is designed so that it will NOT float as well if the coolant concertration is not correct (not enough coolant).

Again, what can happen is the float will stick to the bottom. Once freed up, it will float on its own. If the float is too water logged, it will never float and it can not be replaced (the de-gas bottle is built around it).

Absolutely agreed 100%. He not only provides an answer, but further educates all of us about the what, where and why of the issue. Awesome.
