Electrical Component and Connector Locations
Reference: The following media should be used to locate electrical components and connectors:
- Electrical Schematic
- Parts Manual
- Operation and Maintenance Manual
The following information is a guide to reading the tables on the back of the Electrical Schematic.
- Component Location Tables use white circles to mark the locations in the vehicle profile and area views. Alphabetical letters in the Machine Location Column indicate a general area of the machine. See the corresponding footnote at the end of the table for a location description.
- Harness Connector Location Tables use white circles to mark the locations in the general and area views. Alphabetical letters in the Machine Location Column indicate a general area of the machine. See the corresponding footnote at the end of the table for a location description.
