hey guys, i don't know much about electrical but i bought a 1992 mustang 5.0. I was told the car had power windows etc but the previous owner decided to remove them so the car would be lighter. I opened the door panel up to take a look. I seen this one wire which i took a picture of. Is this the wire for power windows that runs from drivers side and behind the dash to the passenger side? The car also has power mirrors and that wire is already connected and working.
