Help! where does this wire go?

[Justin01gt]

When I installed my header over the weekend I accidentely pulled a wire out that was running into the spark plugs. The spark plug end is still connected but I don't know where the other end goes it looks like the wire was broken. The end that is disconnected has a rubber housing around it and I beleive the wire is green (I think, I don't remember). Anywayz the car starts and runs fine, not even a CEL, I can't find anything that doesn't work, what is this wire for?

P.S. I already looked through the wiring diagrams and couldn't find the wire on there, but I'm not very good at reading them though. Thanx.

I just checked and the wire is pink, not green

hmmm.. not sure man.. do you have a camera to take a pic and maybe I can look at it better..is it one of the wires that connects to your spark plug tubes??

Don't have a picture man, but it is the wire that comes from the spark plugs, and has a spot to exit through the plastic spark plug cover. It is pink and has a rubber housing around the end of it. the housing is shaped like it is ment to plug into something, I don't know but everything seems to be working fine, I'm just a little worried.

wait a second.. are you talking about the wire that say your standing on the front of your engine..its on the left rear side of the valve cover area.. just one single wire hangs down off back side and loooks like it plugs into something.. I wish I could verify the color of it but withoutr a Celica its impossible.. but it doesnt plug into anything..its a sensor :)

Yah, it's the one hanging out of the rear left side, but it has a pink wire that looks like it has been broken, the end is stripped a little. It is a single wire, but to my knowledge I didn't know a wire alone could sense something but everything runs fine, so that is probly all it is. It is just when I saw it unplugged looking like the wire had been pulled loose out of something it got me a little worried. Thanks for your help Larry!
