Well, I'm in the process of installing a Cold Air Intake.. my first one, I'm about 3/4ths done with the installation and all but I wasn't sure what the yellow plug in the picture is? It isn't the air temperature sensor, I was working on the underside of the car when I noticed it hanging down, I didn't pull the yellow plug off of anything without accidentally doing it. Anyone got any quick answers? I'm almost done except for this little tid bit. Thanks, I'll show pics of it when it's finished.

That's your outside temp sensor, I put mine in the airbox so I can see what the engine is picking up for air temps B)

Oh yeah, and if you didn't trash the bracket for the horn, mount it to the place where you mount the cruise control module, works like a charm.

Thanks

Anything but studying for finals tonite. How much was your intake?

It looks like there's some rust on the probe.

Maybe using some steel wool or light wet/dry sandpaper will take it off.

Looking forward to seeing your pics.

I've been wondering what that was. I noticed mine was dragging after I bought my car a couple of weeks ago. I wired tired it up out of the way. Thanks for the info, now I know where it should go.

Hmm..Yea I noticed mine when I was checken underneath my car...I figured thats what it was..mine is in some type of air flow intake that passes through the grill....

Here's the intake from the top

Now, in this picture is a ghetto-way of keeping the air intake sensor in the pipe... do I need to have this sensor in there at all? If so, do you guys have any other ideas of how to keep the sensor in the pipe without putting a string around it like I did?

This is just a temporary solution I hope heh. Thanks

And one more from the bottom....

-Btw, I found a perfect place to put that yellow sensor, right near the air filter I found a hole that it slides all the way into, toward the ground, and it doesn't move around, and also it's cooler in that area where I put it. I put it up near the cruise control actuator and the temp inside the car read 107 degrees heh, after I went driving. Just some thoughts.
