Harness", “Harness Layout”. A coordinate grid is included for complex harnesses to aid in
locating connectors.
26 Ground (GND)
The line spliced and grounded under wire color shows that ground line is spliced at the
grounded connector.
27 Ground (GND)
This shows the ground connection. For detailed ground distribution information, refer to
"Ground Distribution" in PG section.
28 Connector views
This area shows the connector faces of the components in the wiring diagram on the page.
29 Common component
Connectors enclosed in broken line show that these connectors belong to the same compo-
nent.
30 Connector color
This shows a code for the color of the connector. For code meaning, refer to wire color codes,
