2011, Ford Fiesta. When changing the rear side break light, in the boot of the car (rear side), behind the back lights more a less, there is a black box -size of palm of hand-  securely tied with a tie-back to hold it in a discrete place, almost above the back wheel too. Also,  it is behind the carpet in the boot. What could this be? Thanks in advance

Towbar electrics?  Aftermarket parking sensor module?

Might be an updated flux capacitor, or even some back up dilithium crystals?

The photo is difficult to see - however could it be an insurance black box?

 

Anything written on it? Any part numbers/model numbers/serial numbers?

Unplug it and see what stops working.....

Now, you see, I'm of an age where that phrase is entirely innocent 🤣

Hi thanks for the suggestions I understand now it is a sensor module. I initially done a brief google search which told me parking sensors are on the bumpers and from that I presumed it must not be that however after reading your suggestion I’ve googled it again and yes it appears to be the sensor module thanks again
