Diagrams Pathway (slide 2 of 14) You are now viewing all the electrical diagrams for this vehicle. Had you first selected a system or component, you would be viewing the electrical diagrams for the system or component only. However, we selected electrical diagrams from the vehicle level: therefore, we can view all diagrams for every system or component. Popular Mechanics™ provides electrical diagrams by specific circuit, as opposed to books that contain multiple circuits on a single page. This makes them easier to use and understand. Let's look at diagrams for "Instrument Panel, Gauges and Warning Indicators." Please click on that text now.
