HOW TO READ HARNESS LAYOUT
The following Harness Layouts use a map style grid to help locate
connectors on the drawings:

Main Harness

Engine Room Harness LH View (Engine Compartment)

Engine Room Harness RH View (Engine Compartment)

Engine Control Harness

Chassis Harness and Rear Sonar Sensor Sub-harness

Body Harness

Body No. 2 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
