    What is this plug for?

    The other day I noticed a plug hanging under my truck. I thought is was for an o2 sensor but when I layed down under my truck I couldn't tell where it would plug in. Any Ideas?

    Ok, if you can't tell it is right behind my Y pipe. It doesn't look like it will plug into anything close to it. So I am not sure. Any ideas?

    Yes I do have an ory and no cats. My rear o2 were deleted in my tune. So that must be it. Funny it's been like that for 2 years. I guess I never noticed or maybe it was held up by a zip tie and it broke. Oh well I will just ziptie it up somewhere then. Thanks for the replies!
