Explanations

The electrical diagrams below are drawn using a coordinate system such that the ground line is at the bottom. Using coordinate 55 at the bottom of Figure 12.87 as an example, follow the line up past switch S50 to lamp H20, through connector X2 and finally to the number in the box (20). Return again to the bottom of the Figure, to coordinate 20, and you will see that the number 55 in the box matches this coordinate near the top of the diagram. The line running from this number in the square is a continuation of coordinate 55 and indicates the power supply wire for the H20 lamp, which goes through the 20 Amp fuse F6.
