I have this wire located on the Passenger side shock tower, near the ECU. It's part of the engine harness.

I checked on SHBOX.com It's listed as the "AC evaporator Temp sensor" But I don't know where to plug it in ( I don't remember even dis-connecting it)

Here is a pic:

Does your car have air conditioning?

 

Thanks Man:

 

That actually goes inside the car under the passenger dash. It plugs into a small square box about the size of a match box.

i wonder if you are looking at the jumper wire for the fuel pump. it lays on the fender like you said and it isn't connected to anything. go look on shoeboxes site for the fuel pump prime wire and see if thats it. they look alot like each other. makes no sense for the evap wire to be out there unless someone pulled it out of the wire harness.

 

Guess I should have looked at the pic. That strand of wires is kinda hard to get to in my opinion. I think I actually broke mine slightly when taking it out. But if you don't have a/c then don't sweat it.
