What is this?

Found a broken wire under my truck that leads to this thing that looks like some sort of speaker? It's on the rear wall near the passenger side cab door. I looked some more under my truck and found the other end of the wire near the spare tire and it goes up towards the passenger tail light harness I think. I'm guessing it's the backup sensor alarm? Does our trucks have backup alarms that beep when you get too close to something? My bumper seems to have the sensors I believe. But I've never heard them beep. Anyways, what do y'all think this is?

 

It's a backup sensor.

Similar to this:

That looks just like it. It doesn't look like it was OEM, I'm wondering if the previous owner installed it himself, does anyone know what the OEM one looks like or if we even have one on our trucks?

 

No idea. Maybe you take the truck to the dealership and have a guy from parts dept walk with you back to the truck and show it to him. Maybe he knows something. It could be either aftermarket or OEM..

If it was me, I think it's an aftermarket item.

 

Why would they put it inside the cab??

 

Do not believe the 2nd cam with a back up sensor. Just camera but no warning buzzer.

 

Not some thing from Toyota. That's not factory wiring it's a poor job.
