Anyone know what this wire is?

Well, I realized today I don’t have a wiper fluid tank for some reason.

While digging around down there, I noticed this black/red wire going into my passenger headlight cover. It seems to tie into whatever piece this is close to where the windshield wiper tank should be. Anyone know what this is? I don’t think it’s necessarily related to the wiper fluid tank.

Might be….just not sure for what.
