HELP! Rear O2 sensor

I don' know how the hell it got caught but while I was pulling my stock exhaust off the rear O2 sensor came with the exhaust.

Now I cant find where the hell it pulled from.

Here is what it looks like.

I have a 2011 Fatboy lo.

Any insight?

Any help would be much appreciated.

The last bikes I worked on were an 08 FXSTC and an 09 rocker. You may be able to see the clip that holds it to the bottom of the oil tank if you pull the battery. Worked for me.

One of the problems is that people are trying to unscrew their O2 sensor with it still plugged in. That is a big NONO. You can and will damage the wires going into it. The plug is under the oil tank. It's not too hard to get to from the right side of the bike. What might also work good is to remove the battery and tray from the oil tank and the plug should then be right there looking at you.

Just dealt with this same issue this weekend.. the wires actually pulled out from the plug. As mentioned mine was located under the oil tank, I found it was easiest to pull the battery out and fix.
