Ground Distribution
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
See appropriate OEM WIRING DIAGRAMS - GROUNDS article contains the schematic that shows the complete details for each ground connection or main ground splice. This is useful in diagnosing a problem affecting several components at once (poor ground connection or ground splice). All details (wires, splices, connectors) between the ground point and the component are shown in illustration. These ground connection details are shown in illustration here in order to keep the individual cell schematics as uncluttered as possible.
