Installation
Tools & Parts Required
Installation of the VDC requires the following tools and parts:
Electric Drill Rubber grommet assortment*
Crimp tool Ring terminal assortment"
Screwdriver Butt connector assortment*
Pliers Heat Shrink Tube*
Heat gun or mini-butane torch Self-drilling screws*
2 Conductor shielded Cable* Convoluted ’I’ube*
* These parts are supplied with the VDC installation kit, Scully Part Numbers 09302
and 09305. Installation Kit 09302 is for use with the VDC Scully Part Number 001403
(VDC without connectors). Installation Kit 09035 is for use with the VDC Scully
Part number 001402 (VDC with connectors). All kit terminals and connectors contain
corrosion protection gel. One tube (2 oz.) of corrosion preventive compound for
electrical contacts is provided with the kit for any connections that do not have
protection gel.
VDC Mounting Location
Select a suitable location for the VDC, preferably where wiring connections are
protected from excessive heat, water, oil, or other agents which could be harmful
to electronic components. The VDC is designed to withstand vibrations in road
transport However, it should not be subjected to any mechanical impact Sufficient
room should be lefi around the installation area to connect wires to the VDC. Prepare
the surface by cleaning away all dirt and oil where the unit is to be mounted, make
sure it is at least 3 feet from the fuel tank inlet. Mount the VDC using self—drilling
screws at two diagonal outer holes. VDC installation kit is supplied with self-drilling
screws, however, drilling pilot holes might be required on some installation.
Good power and ground connections are critical for proper VDC operation. If extra
Wire is needed to reach the battery post, use the 2 conductor shielded cable The
VDC black wire must be grounded to the negative battery post The VDC case is
isolated from its electronic circuit, therefore the chassis does not provide a reference
ground. Cut the drain wire on battery connection end and ground the drain wire at the
VDC end. The VDC red wire is connected to constant HOT (battery voltage) and must
be from a constant power source. For negative ground vehicles, you can use one of the
eidsting VDC mounting holes as the drain wire ground point, as long as it is mounted
on a metal surface with a good chassis gound.

2.4 Odometer Transducer Location
2.4.1 Electronic Odometer/Speedometer
The optional odometer/speedometer transducer is a device that converts mechanical
rotation to electronic pulses so that the VDC can calculate mileage. Vehicles with an
electronic odometer/speedometer or an electronic dashboard already have electronic
sensor. This sensor is usually found where the transmission or transaxle connects to
the drive shaft. For such vehicles, connect the two wires from the VDC harness (white
and black/white) to the odometer/speedometer cable. The vehicle speed sensor should
be wired to the VDC with correct polarity to guarantee that the high to low transition
occurs on the “clean" side of the sine wave (see Figure 1). If the connection is made
with wrong polarity, reverse the connection.
Starting from the VDC, run the white and black/white harness wires to where the
electronic sensor is located. Crimp harness wires to sensor wires by using one of
the following recommended methods.
if t CAUTION
When routing wires or cables, it is Important to keep away
from any moving parts, and any parts that generate excessive
heat, or areas that may impede safety. Keep away from drive
shafts, fan blades, belts, adjustable steering column, foot
pedals, radiator, and exhaust system.

2. Cut and place 1.5“ of self sealing heat shrink tube over one end of sensor Wire.
3. Strip off 1/4’I of insulation from the VDC white wire. Twist the stripped VDC wire
together with one of the sensor wire.
4. Crimp a butt splice connector onto the twisted wirm. Crimp the other side of the
connector onto the other stripped sensor wire.
5. Place the heat shrink tube over the butt connector.
6. Use a heat gun, or mini-butane torch to shrink and seal the tubing. Shrink the
mbing to form a moisture~tight seal around the wire when heated.
7. Use the above procedure to crimp the VDC black/white wires to the other sensor
wire (stagger the connection).
WARNING
When heating the shrink connector, make sure it is positioned at least
3 feet from fuel lines or batteries, in order to avoid an explosion.
Cover harness wires with 6 inches of convoluted tubing. Using cable fies, secure
the harness wires to the chassis supports. Be sure to leave some slack and provide
sufficient clearance from any moving parts, brake or steering components. Leave
at least 4 inches of clearance from any ignition system win'ng or hot surfaces. Do not
attach the wires to any moving parts, pneumatic or hydraulic lines or to clutch to
brake cables. If the wires must be run along the chassis, it must be routed away
from exhaust pipes, and it must be protected from any object which could strike it.

Engine Hours Connection
For the VDC to record engine hours, VDC's yellow wire must be connected to a point
in the vehicle that provides HOT (battery voltage) signal while the engine is ON or
running, and OFF (zero voltage) when the engine is off. Check the vehicle’s wiring
diagram to determine the best connection point. Suggested connection points are an
existing hour meter, the positive side of the oil pressure switch, or the switched side
of ignition key. Verify that the connection point is one where the battery voltage is
present when the ignition switch is on, and is open or grounded when the switch is off.
Follow one of the recommended Methods A or B, to make your connections

2.6 Transmitter Coil (T-Ring) Mounting
WARNING
When performing any work around the fuel tank inlet be sure to
comply with all applicable federal, state, local and other applicable
codes and regulations as well as the requirements of NFPA—30
“Flammable and Combustible Liquids Code". When applicable,
European CENELEC requirements must be complied with. Do not
smoke or perform any metal work with the fuel tank cover removed,
or when fuel vapor is present. Do not perform any operation which
may impair the fuel tank or fuel pipe safety. Use only pneumatic tools
for metal work.
The VCOMM packets are sent electromagnetically from the VDC through a transmitter
coil (T—Ring) on the fuel tank inlet, to a receiving coil on the refueling nozzle (N—Ring).
One T-Ring should be installed around each fuel tank inlet with the mounting ears
down (two T—Rings per VDC maximum). The T-Ring should be positioned as close to
the fuel tank opening as possible, preferably within four inches due to Nozzle Ring
(N-Ring) sensitivity. Two sizes of T-Rings are available; 27" ID and 4.7” ID. The 2.7" ID
T—Ring fits most passenger cars, light trucks, and buses with 2—1/2“ fill pipe. The 4.7" ID
T-Ring fits truck saddle tanks with 4—1/2" fill piper T-Rings have a thin flexible flange
inside a rigid outer ring that keeps them in place on the fuel tank. They are supplied
with approximately 12 inches of wire and must be extended using the coil harness
and/or two conductor shield cable Scully part number 000766i Use Method B - Using
MOIS'I'URERESISTANT Butt Connectors to make your connections.
if j CAUTION
When routing the T-Ring wires, be sure to keep it at least
2 inches from any other wires in order to preserve the intrinsic
wiring requirements.

Installation
Before beginning the installation, have the fuel pipe repaired or replaced if it shows
any signs of leakage or excessive wear. Check to make sure that the fuel inlet cover
fits tightly Position the T-Ring around the fuel tank inlet and check to make sure that
there is suficient room to remove and replace the fuel inlet cover. The T—Rings are
designed to be held in place by fitting the diaphragm over the fuel tank inlet neck.
In cases where the coil mounting ears are unused, and interfere with proper fit, the
ears may be removed. Be careful not to cut into any wires within the coil.
The mounting eais provide an alternate method of attachment. External threaded
adhesive studs (Click Bond CS sefles) should be positioned to accept the mounting
ears. Since power tools can not be used in a Class I, Division I location, me of studs
is strongly recommended. Please consult Click Bond (702) 885-8000 for your specific
application. Ifdrilling a hole is absolutely needed, you must remove the shroud and
take it to a safe place to drill hole, then ire—attach the shroud.
Cover the T-ring wires and connections with a 12 inch piece of convoluted tubing.
Add a cable tie at the neck of the T-Ring to keep tubing in place.
Optional Harness Assembly
The optional harness assembly is provided to reduce the installation time. The harness
contains weatherproof connectors with suitable length of wires for a typical vehicle
installation. VDC T-Ring wiring is provided via a short harness and must be extended
using the coil hamess and two conductor shield cable Scully part number 000766.
T-Ring wiring should run along the vehicle side on which the fuel tank inlet is located.
T-Ring harness should have a minimum clearance of 2" from all other wires and the
harnesses.
