PRECAUTIONS BEFORE SERVICE
WIRING HARNESES
1. Secure the wiring harnesses by using clamps so that there
is no slack. However, for any harness which passes to the
engine or other vibrating parts of the vehicle;allow some
slack within a range that does not allow the engine vibra-
tions to cause the harness to come into contact with any
of the surrounding parts. Then secure the harness. by
using a clamp.
In addition, if a mounting indication mark (yellow tape)
is on a harness, secure the indication mark in the speci-
fied location. (C 1638 1)
2. If any section of a wiring harness contacts the edge
of a part, or a corner, wrap the section of the harness
with tape or something similar in order to protect it
from damage.
3. When using a circuit tester to perform continuity or volt-
age checks on connector terminals, insert the test probe
from the harness side.
If the connector is a sealed connector, insert the test
probe into the hole in the rubber cap for the electrical
wires, being careful not to damage the wire insulation.
Continue to insert the test probe until it makes contact
with the terminal.
4. When disconnecting a connector, be sure to pull only the
connector, not the harness.

PRECAUTIONS BEFORE SERVICE
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.
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.
(3) If an ammeter or similar instrument is to be con-
nected to a live-wire circuit, use tape to protect the
wire, use. a clamp to secure the wire, and make sure
that there is no contact with any other parts.
(4) Be sure to provide a fuse for the load circuit of the
optional equipment.
