I changed my o2 sensor last night, and there is a wire, that is next to the o2 wire (the 02 and this wire are held together by a little plastic clip) and now i can't find where it goes? if you know what this wire is supposed to go to (if anything) let me know PLEASE. also my temp guage stopped working after i switched the o2, could this wire be related?

Engine is an L03.

Thanks in Advance.

If the wire is dark green, it goes to the temp gauge sender, which is between the #1 & #3 spark plugs.
