I know exactly where the transiever is, it is on the left side in the trunk as high as possible. Everyone always overlooks where it is because it is hard to see. If you remove the left side trunk trim panel the box is horizontally mounted positioned front to rear and is @10 in long by 4" by 1" It is by the trunk seal. I don't have a pic of that year on file otherwise I would be posting it!
