Because more than one electrical system is located in each subsection, each electrical system's schematics are further broken down into operating systems, or cells. Each set of electrical system schematics will have a cell number that remains common across all vehicle platforms. Cells are organized by subsystems with most containing a circuit schematic and the associated text. For example, the cruise control schematic will always begin in cell 34. The other information for cruise control follows.

Some sections may have more than one circuit schematic, such as Power Distribution, Interior Lights and Air Conditioning.
