I've searched and searched and have not found anything that comes close to answering my question.

My o2 sensor on my dump is always getting power key on or not. It already ruined my old sensor and has killed my battery a number of times. I have a new sensor and am ready to install it but I don't want to ruin my new sensor. I know the brown wire is supposed to be switched hot. So my question is, where does the brown wire go once it joins the main harness?

If I can't get an answer I'm going to cut into the wire and install my own relay to come on with the key.

Any help would be great. Thanks everyone.
