What is this part?

This weekend I did the PITA DIY to replace the CVV on my car (if it fails again I'm not doing it again) and thought I damaged a wire. This cable originates from the wiring box and only has a single brown wire that goes to the connector. I'm sorry if the picture is not the best but I'm just curious to know what this single wire cable goes to. I always thought at a minimum anything electrical would require two wires but this one did not and I thought I broke the other wire during my battle with the CVV install. In the end, the car is not throwing any errors or codes so I'm assuming this is supposed to be this way. Anyone have a clue what this is? Again, the picture is bad I know... the space was limited and the flash didn't illuminate the area well enough.

Brown wires are usually Grounds, but I'm sure some of the CVV experts can confirm that.

The connector for the oil pressure switch has a single wire. Check the back of your oil filter housing.

This sounds highly probable. I'll have to double check under the hood to confirm. Thanks for the feedback Burdell and everyone else as well. Much appreciated.

Oil pressure sensor comes to mind for me as well. The wiki has a chart that shows where each connector should go, BTW. I'm sure you'll find the vacant plug-mate with a little looking around.
