ELECTRIC WIRING INFORMATION
1. CONFORMITY WITH FMVSS 108
All incomplete vehicles manufactured by Nissan Diesel Motor Co.,Ltd.
conform to FMVSS 108 according to the terms and conditions stated in
the Document for incomplete Vehicle accompanying each incomplete
vehicle, except for the lights fitted during body installation. Electrical com
-
ponents installed during body installation,i.e., those which are not pro-
vided or are temporarily installed on the incomplete vehicle, must be
properly installed by subsequent stage manufacturers according to para
-
graph 4 below. It is the responsibility of intermediate and final stage man-
ufacturers to assure that the completed vehicle complies with the
pertinent FMVSS and other applicable governmental requirements.
2. GENERAL
(1) When storing the vehicle, disconnect the battery ground (negative)
terminal to reduce the possibility of battery run-down.
(2) The chassis-cab wiring is complete, except for those electrical compo-
nents required by addition of the body. Alterations to electrical com-
ponents required for body installation should be kept to a minimum.
Alteration that may influence existing circuits should be avoided to the
extent possible. When an alteration which may affect existing wiring
cannot be avoided, follow the instructions in paragraph 3.
(3) Control Unit
• When arc welding, remove all control unit connectors.
• Do not tamper with the electronic control circuit.
(As making a branch connection, etc.)
• The control unit power supply fuse and the pre-stroke power
supply fuse are for exclusive usage.
Do not replace with other types. (light, radio, etc.)
3. WIRING CIRCUITS
(1) Adding or Modifying Circuits
Follow the instructions below when adding a new circuit or modifying
part of an existing circuit.
• Install wiring to avoid metal edges, bolts, and other abrasive surfaces.
If such cannot be avoided, use a suitable protector to protect the wires
and, to the extent possible, cover edges and abrasive surfaces with
appropriate protection.
• When routing wiring through a hole drilled in metal, fit a flange in the
direction of penetration, or install a grommet on the hole edge.
• Avoid routing wiring where the temperature exceeds 176°F (80°C). If
such cannot be avoided, heat-resistant wiring, heat insulation and
heat shields must be used.
• Avoid routing wiring near brake fluid lines or fuel lines to reduce the
possibility of corrosion and fire form short circuit. If such cannot be
avoided, route the wiring above the brake and fuel lines.
• Avoid routing wiring where it may be susceptible to damage from road
debris, particularly below the frame where it is extremely vulnerable to
rocks, brush and other off road hazards. If such cannot be avoided,
protect the wiring, connector plugs and receptacles with protective
shielding.
• Avoid routing wiring where it is susceptible to ice damage.
• When installing wiring in areas of motion, secure the wiring and pro-
vide sufficient slack or loop to allow for the motion. Avoid wiring in
areas where moving parts may pinch or damage the wiring.
• When adding new wiring, use clips and secure the wires firmly with
clips. Avoid clamping damage to wiring.
• Avoid loops, dangling and loose wires except as noted in areas of rela-
tive motion.
• Route wiring such that terminals, plugs, receptacles and other compo-
nents are not exposed to moisture.
• Avoid wiring in areas subject to vibration.
• When installing wiring, avoid damage to terminals and connectors.
• Use appropriate connectors when adding new wiring to existing wiring.
