ELECTRICAL COMPONENTS
1. When installing any of the vehicle parts, be careful not to
pinch or damage any of the wiring harnesses.
2. Sensors, relays, etc., are sensitive to strong impacts.
Handle them with care so that they are not dropped or
mishandled.
3. The electronic parts used for relays, etc., are sensitive to
heat, If any service which causes a temperature of 80°C
(176°F) or more is performed, remove the part or parts in
question before carrying out the service.
FUSES AND FUSIBLE LINKS
1. If a blown-out fuse is to be replaced, be sure to use only a
fuse of the specified capacity. If a fuse of a capacity larger
than that specified is used, parts may be damaged and the
circuit may not be protected adequately.
Caution
If a fuse is blown-out, be sure to eliminate the cause of
the problem before installing a new fuse.
2 If additional optional equipment is to be installed in the
vehicle, follow the procedure listed in the appropriate
instruction manual; however, be sure to pay careful
attention to the following points:
(1) In order to avoid overloading the wiring, take the
electrical current load of the optional equipment into
consideration, and determine the appropriate wire size.
(2) Where possible, route the wiring through the existing
harnesses.

HOW TO READ WIRING DIAGRAM NOEDBAE
HOW TO READ CONFIGURATION DIAGRAMS
(1) Connector symbols
A wiring diagram shows the installed condition of each connector in a schematic style. The connectors are
shown and classified as follows, depending on their locations and are marked by connector symbols.
In case connectors of the same shape (same number of wires) are centralized, their colors are indicated for
identification.

(4) Indication of fuses, fusible links and centralized relays
The fuses and fusible links in a circuit diagram are indicated by a wave symbol (-) and a double wave symbol
(~1, respectively. At a centralized junction, the fuses are given fuse numbers and centralized relays are given
connector symbols.
Example of centralized junction symbol: A - 01 x
Centralized junction indication symbol
Connector’s unique number (serial number)
Connector symbol
(5) Indication of ground point
The ground point in a circuit diagram is marked by a ground symbol, making it possible for you to refer to a
wiring harness configuration diagram and to ELECTRICAL SYSTEM PARTS LOCATION (Grounding).
(6) Indication of wires
In a circuit diagram, the wire diameter and wire color are shown for each wire. If there are several wires
of the same color in a connector, their wire color indication symbols should be such symbols as “I and
“2 for identification.
On connectors like this one given a central-
