Section Identification and Information
DESCRIPTION - SECTION IDENTIFICATION AND INFORMATION
The wiring diagrams are grouped into individual sections. If a component is most likely found in a particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, the Auto Shutdown Relay is most likely to be found in Powertrain Management, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.
Splice diagrams show the entire splice and provide references to other sections the splices serves. Splice Information only contains splice diagrams that are not shown in their entirety somewhere else in the wiring diagrams.
Connector Pin-Outs shows each connector and the circuits involved with that connector. The connectors are identified using the name/number on the diagram pages.
