Default Outside Temp Sensor Location

Does anyone know where to find pics or a diagram of where exactly the outside temp sensor is located. I found it in front of the bumper but i cant find where it ends (the actual plug part).

I have the sensor ready to be plugged in but cannot find any information on exactly where you plug it in. Are there some parts I need to take off further to get to it...

i was under the impression this was an easy fix from what everyone else has been saying.

IIRC it's a connector under the power steering res cover thingy.

I tried following the sensor from the outside and it seems to disappear within another wire to where I can't get to it.

From everything I found online surrounding this topic, it seems that it should be easy to do without having to go a mchanic or disconnect anything else...

am I right about this?? does anyone have a picture or at least a diagram of where its located?

Default should it be a sensor AND wire replacement?

or should the sensor unclip from the wires at the bumper?? dealer gave me sensor that was attached to its own wire but mechanic told me it should unclip at the wire? pics? anyone? bueller?

Default hey

it ends where u put in power steering fluid or hydraulic fluid whatever u want to call it. if ur looking down at ur engine its to the right behind the drivers headlight. there is a green cap and a black plastic cover that comes off and under it are three connectors. one of them being the other end of the sensor.

The problem is I cant figure out which one the plug is and the new sensor definatly doesnt seem to be able to reach that far... im thinking that there is a connecter/extendor wire thing and im supposed to plug it in behind the bumper
