Newbie here... Can you name this part

[brs79]

Greetings,

Here’s the haps, my serpentine belt broke and apparently tore this wire off of its connector.

It looks like I can unscrew this piece, but not sure if I have to replace the whole wire assembly.

Any advice would be great & yes this bad boy def needs some serious engine wash.

Also its a 2013 bmw X5 6cyl.

Thanks again
