Where to Find Electrical Schematics

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

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 be located in the cruise control subsection and the schematic title will begin with cell 34.

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