HOW TO READ HARNESS LAYOUT
The following Harness Layouts use a map style grid to help locate
connectors on the drawings:
lMain Harness
lEngine Room Harness
lEngine Control Harness
lChassis Harness
lBody Harness
lRoom Lamp Harness
lDoor Harness
To use the grid reference
1. Find the desired connector number on the connector list.
2. Find the grid reference.
3. On the drawing, find the crossing of the grid reference letter column and number row.
4. Find the connector number in the crossing zone.
5. Follow the line (if used) to the connector.
CONNECTOR SYMBOL
Main symbols of connector (in Harness Layout) are indicated below.
