I have a 1997 saturn sc2. In the trunk of my car there was a wire dangling down from the top when i bought it. Asked seller and he didnt know. It is not the trunk light wire or has to do with any of the tailights,blinkers,brake lights. It looks like a factory wire. It has a bunch of holes in the connector.
it might be a connector for a cd changer. if it has a factory radio with a cd button, but no in-dash cd slot, that could be what youre lookin at. sounds like a square plug? maybe 10 or 12 holes?
what color is the wire? i ask because i have a wiring diagram.
