Electrical Wiring

The electrical circuits have been designed in particular
with the emphasis on safety. In this respect, a high-
current fuse box is provided at the side of the battery
in order to prevent fires caused by shorting during
accidents. Therefore, follow the procedures below
when making changes to the electrical circuits.

• Additional Wiring

(a) Use wires of the same gauge and color as the

original wires when making wiring extensions.
When selecting a cable size, make sure that its
allowable current conforms to the system
rating. Especially in a system where a motor,
etc. is used as a load, allow for the current in
case the motor locks (restricted).

(b) Connect wires securely by soldering or crimping

terminals and then insulate them completely
with tape or other weatherproof material. Never
attempt to connect wires by just twisting the
stripped ends together.

(c) Do not use sulfuric acid for soldering.
(d) Do not extend or shorten the battery cables. If

battery cable length must be adjusted due to
the transfer of the battery, replace the cable(s)
with one(s) of appropriate gauge and length.

(e) Be especially careful not to modify the type of

clamps, location, or slack of wiring connected
to movable components between the starter
and the frame.

(f) Wiring should be made along the rear body

parts, the frame, etc., fully supported, and
never extended individually in midair.

(g) Clamp all wires securely in locations away from

moving parts or sharp corners on the chassis
and body. Use grommets where routing wires
through metal plates in order to prevent
electrical short circuits due to installation
damage or chafing. (Fig. 1)

Risk of accident

Before installing any attachments, special-purpose
bodies, equipment or carrying out any
modifications to the basic vehicle and/or its
assemblies, you must read the relevant sections of
the Owner’s Manual, as well as the operating and
assembly instructions issued by the manufacturer
of the accessories and items of optional equipment.

You could otherwise fail to recognize dangers,
which could result in injury or death.

Work incorrectly carried out on electronic
components and their software could prevent this
equipment from working correctly. Since the
electronic systems are networked, this might also
affect systems that have not been modified.

Malfunctions in the electronic systems could
seriously jeopardize the operating safety of the
vehicle.

(h) Wires should never pass along brake tubes or

fuel lines. Observe the following clearances.

(i) Position wires more than 200 mm {7.87 in.}

away from parts which become extremely hot
such as the exhaust pipe or muffler. Install a
heat insulator if heat protection is necessary.

(j) Road debris which is thrown up by the wheels

can damage wiring. Install metal covers to
protect the wiring.

(k) Tape wires together with the nearest chassis

wiring harnesses if possible.

(l) Route wires along the chassis harnesses that

are already installed. Wires should be clamped
with vinyl tape, and wrapped up widely with thin
metal sleeves (rubber or vinyl coated, or wiring
loom). Do not use weak vinyl tape that could fall
off soon due to engine heat.

(m)Wires connecting engine and transmission

components should run along previously
installed harnesses to allow them to absorb
motion. Also allow adequate slack to prevent
them from contacting other components.

(n) When connecting plugs, place the female end in

the power source side to prevent a short circuit
to the body even if the terminal comes off.

(o) Use coated or vinyl clamps when clamping

wires.

(p) Bonding or temporary clamps should be used

only for additional support.

(q) Use standard wiring clamp intervals as shown

below:

(r) Wires may come in contact with edges of metal

parts; increase the number of clamps and cover
the edges with protectors to prevent damages
due to vibrations.

floor, use the grommets in the area A and B
shown in Fig. 4.
