Nissan Murano (Z52) 2015-2024 Service Manual / General Information / General Information :: How to Use This Manual / How to Read Wiring Diagrams

Connector Symbols

Most connector symbols in wiring diagrams are shown from the terminal side.

Connector symbols shown from the terminal side are enclosed by a single line and followed by the direction mark.
Connector symbols shown from the harness side are enclosed by a double line and followed by the direction mark.
Certain systems and components, especially those related to OBD, may use a new style slide-locking type harness connector. For description and how to disconnect, refer to PG section, “Description”, “HARNESS CONNECTOR”.
Male and female terminals

Connector guides for male terminals are shown in black and female terminals in white in wiring diagrams.

Sample/Wiring Diagram -Example-

Each section includes wiring diagrams.

Description
No.	Item	Description
1	Power supply	This means the power supply of fusible link or fuse.
2	Fuse	“/” means the fuse.
3	Current rating of fusible link/fuse	This means the current rating of the fusible link or fuse.
4	Number of fusible link/fuse	This means the number of fusible link or fuse location.
5	Fusible link	“X” means the fusible link.
6	Connector number	Alphabetic characters show to which harness the connector is placed. Numeric characters show the identification number of connectors.
7	Switch	This shows that continuity exists between terminals 1 and 2 when the switch is in the A position. Continuity exists between terminals 1 and 3 when the switch is in the B position.
8	Circuit (Wiring)	This means the wiring.
9	Shielded line	The line enclosed by broken line circle shows shield wire.
10	Connectors	This means that a transmission line bypasses two connectors or more.
11	Option abbreviation	This means the Nissan Murano vehicle specifications which lays out the circuit between “”.
12	Relay	This shows an internal representation of the relay.
13	Optional splice	The open circle shows that the splice is optional depending on Nissan Murano vehicle application.
14	Splice	The shaded circle “” means the splice.
15	System branch	This shows that the circuit is branched to other systems.
16	Page crossing	This circuit continues to an adjacent page.
17	Component name	This shows the name of a component.
18	Terminal number	This means the terminal number of a connector.
19	Ground (GND)	This shows the ground connection.
20	Explanation of option description	This shows an explanation of the option abbreviation used on the same page.

SWITCH POSITIONS

Switches are shown in wiring diagrams as if the vehicle is in the “normal” condition.

A vehicle is in the “normal” condition when:

Ignition switch OFF”.
Doors, hood and trunk lid/back door are closed
Pedals are not depressed
Parking brake is released

MULTIPLE SWITCH

The continuity of multiple switch is described in two ways as shown below.

The switch chart is used in schematic diagrams.
The switch diagram is used in wiring diagrams.

Connector Information

Description
No.	Item	Description
1	Connector number	Alphabetic characters show to which harness the connector is placed. Numeric characters show the identification number of connectors.
2	Connector type	: Connector model : Cavity : Male (M) and female (F) terminals : Connector color : Special type
3	Connector color	This means the color of a connector.
4	Terminal number	This means the terminal number of a connector.
5	Wire color	This shows a code for the color of the wire.
		B = Black W = White R = Red G = Green L = Blue Y = Yellow LG = Light Green BG or BE = Beige BR = Brown	LA = Lavender OR or O = Orange P = Pink PU or V (Violet) = Purple GY or GR = Gray SB = Sky Blue CH = Dark Brown DG = Dark Green
		When the wire color is striped, the base color is given first followed by the stripe color as shown below: Example: L/W = Blue with White Stripe
6	Connector	This means the connector information. This unit-side is described by the connector symbols.
