The Ford Transit Body and Equipment Mounting Manual documents ground points in a set of diagrams and tables starting in section 4.20.1 on page 211. While most of the ground points illustrated in the diagram are coloured black, a few are green. The significance of this colouring does not appear to be explained in the manual.
There is some, but not complete, overlap between the set of green ground points and the set of ground points denoted with asterisks in the table. There are both green ground points that are not annotated with asterisks and ground points annotated with asterisks that are not green. The meaning of the asterisk is also not completely clear but I think it is meant to indicate that these points are preferable in cases where it is necessary to use more than one eyelet per ground stud.
What does the green colouring on some of these ground points indicate?
