The car is a Volvo S40 2005.
Before I can really go any further, does anyone know what this is for?
My car is very clean.
Its in the back right bumper of the car. When I flip the thing open there is about a 2 inch depth square then looks like a little pipe inside, Im not sure where it leads. I was thinking it might be for the backup sensors which is an option. Maybe I can use it to wire the backup camera. There is no keyhole in the trunk and screws are the only thing near the back handle. If this can be used to wire a camera I then have to find a camera. If it can not im not really sure what Ill do.
