Location of Electrical Components
The Electrical System Schematic, Parts Manual and Operation and Maintenance Manual should be used to locate the electrical components and connectors.
The following information is a guide to reading the tables on the back of the Electrical System Schematic.
- The "Component Location" table uses white circles to mark the locations in the profile of the vehicle and in the area views. Alphabetical letters in the "Machine Location" column indicate a general area of the vehicle. Refer to the corresponding footnote at the end of the table for a description of the location.
- The "Harness Connector Location" table uses white circles to mark the locations in the general view and in the area views. Alphabetical letters in the "Machine Location" column indicate a general area of the vehicle. Refer to the corresponding footnote at the end of the table for a description of the location.
