The wiring harness diagrams clearly show the connector locations and harness routines at each site on
actual vehicles. Some variations are included in one configuration diagram. Accordingly, some diagrams may
not be applicable for individual vehicles.

A-17

A-18

A-19

Denotes connector No.
The same connector No. is used throughout the circuit diagrams to facilitate connector location searches.
The first alphabetical symbol indicates the location site of the connector and a number that follows is the unique number.
Numbers are usually assigned to parts in clockwise order on the diagram.

Example: A-19

Number specific to connector (serial number)

Connector location site symbol
A: ENGINE COMPARTMENT

F: FRONT FLOOR AND ROOF

B: ENGINE

G: REAR FLOOR AND UNDER FLOOR

C: TRANSMISSION

H: DOOR

D: DASH PANEL

I: BACK DOOR

E: FLOOR CONSOLE

Denotes ground point.
Same ground number is used throughout circuit
diagrams to facilitate search of ground point.
Refer to GROUP 70 SINGLE PART INSTALLATION
