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
