Alternator - police
The high-output alternator provides 200 amperes of current to support
the high power requirements of modern police equipment. Output at idle
is approximately 130 amperes. Current demand by both the vehicle and
all energized police equipment in excess of this amount during vehicle
idling will place the electrical system into a discharge condition.
Electrical power management systems should be applied if necessary to
avoid discharging the battery.
Power distribution connector
Power for aftermarket equipment can be obtained from the power
distribution connector located under the glove compartment. This
connector contains several fused power feeds and inputs available for the
addition of accessories. The following tables show the circuits available
for equipment.

The mating connector is provided on the end of the power distribution
connector. The vehicle modifier can either purchase pins for the mating
connector and install them on the wires before they are inserted into the
connector, thereby avoiding any splicing, or purchase an optional power
pigtail for the interface. The power pigtail (P/N 14A411) plugs into the
power distribution connector and provides blunt cut wires ready for
splicing by the vehicle modifier.
See thePolice Interceptor Modifier Guidefor more details.
Rear power point - police
The rear power point is a battery access port for police auxiliary
equipment mounted in the trunk. It is capable of supplying 80 amps of
battery power. The front power distribution box (PDB) contains two
50 amp fuses, which protect the power point. Battery access is via two
studs contained in an enclosure, mounted in the trunk, on the right side
fender support. The terminal with the red wires is the battery positive,
and the terminal with the black wire is the ground. Remove both fuses in
the front PDB before removing the cover to the rear power point. Ensure
load devices can be turned off, and are switched off when reinserting
fuses.
WARNING:Under no circumstance should the rear power point
cover be removed without first pulling the two fuses in the front
power distribution box. Removing cover without pulling fuses could
result in an electrical hazard, and result in personal injury. Shut off
load devices before inserting fuses.

Headlight flashers (wig-wags) - police
An interfacing connector is provided on the headlight circuit for use of
the headlights as alternating flashers (wig-wags). The connector is
located in front of the radiator. A protective cap is attached to prevent
contaminants from entering the connector when a wig-wag module is not
installed. When installing a headlight flasher (wig-wag) module, remove
the connector and tape it to the wigwag module harness. This will ensure
that the cap is available to be reattached if the wig-wag module is
removed. For additional information, refer to theCrown Victoria
Wiring Diagram Manual.
If your vehicle is equipped with one of the optional Police Interceptor
Equipment packages, the connector will already be used by the supplied
wig-wag module that comes with the option package.
Note:Use of the wig-wag feature overrides normal operation of the high
beam headlights, including flash-to-pass. However, the low beam
headlights will remain on and unaffected.
HEAVY DUTY SUSPENSION - POLICE
This option includes certain heavy duty components that contribute to
the vehicle’s stability and road handling capability under extremes of
operation. The police vehicle has a heavy duty steering gear, extra
control shock absorbers and heavy duty front and rear stabilizer bars.
COOLERS
It is strongly recommended that auxiliary devices such as lights not be
installed at the grille. Such devices will reduce airflow through the grille
and could potentially impact the cooling system performance.
Oil cooler - police
The 4.6L engine has an engine oil cooler to maintain engine oil
temperatures.
Engine and transmission coolers
External transmission and power steering coolers are located behind the
grille and in front of the radiator. It is strongly recommended that
auxiliary devices such as lights and sirens not be installed in the air path
of these coolers as they will impact cooling system performance.

WHEELS/TIRES/BRAKES
Wheel rims - police
To withstand the demands placed on vehicles driven under heavy duty
service conditions, Ford Motor Company installs heavy duty steel wheels.
Tires - police
Tires (including the spare) are speed-rated radials for police use. Use
only the recommended tire size and speed ratings.
In regions with snow and ice during the winter months, installation of
snow tires may be desirable. Snow tires will usually exhibit a drop in dry
pavement handling, but many show an increase in snow and ice traction.
When snow tires are used, they should be installed on all four wheels,
never on the drive wheels only.
Tires - long term storage
Most high performance tires are made with a nylon overlay.
As such, the following steps should be taken to avoid flatspotting when
the vehicles are not used for a period of time.
•Fleets should store the vehicles with 44 psi (303 kPa) in the tires.
•If the vehicle is stored for periods longer than 30 days, it should be
moved several feet at least once during each 30-day period, so that a
different portion of the tread contacts the ground.
•Tire pressure should be reduced to the recommended pressure shown
on the vehicle certification label before the vehicle is placed back into
service.
Training the tire pressure monitoring system (TPMS)
All Crown Victorias are equipped
with a tire pressure monitoring
system (TPMS) that illuminates a
low tire pressure warning light on
the instrument cluster when one or
more of your tires is significantly under-inflated.

Each road tire, as well as the spare,
is equipped with a tire pressure
sensor fastened to the inside of the
rim, opposite (180 degrees) from
the valve stem. The signal from each
transmitter is digitally unique to
avoid interference from transmitters
on other nearby vehicles.
Note:The spare has a TPMS
sensor, but is not programmed to
the module.
Changing tires with a TPMS
Care should be taken avoid damaging the sensor and band during
mounting or dismounting. Please refer to the Crown VictoriaWorkshop
Manualfor the complete mount and dismount procedure. This is critical,
as the procedure is different from previous model years due to the
introduction of the TPMS.
When a new tire/wheel is installed,the TPMS sensor located in the
new tire/wheel needs to be “trained” to the vehicle.
TPMS training tools,such as P/N 8C2Z-1A203-A, can be purchased
from any Ford dealer for use by the driver or shop technician for training
the system after maintenance has been performed that requires system
training. The Tire Pressure Monitor Activation Tool, P/N 204-363, has
more functionality and is designed primarily for shop use. For either tool,
follow the training instructions as outlined below.
Note:This procedure is also included in the Crown VictoriaWorkshop
Manual.
TPMS reset tips:
•To reduce the chances of interference from another vehicle, the TPMS
reset procedure should be performed at least three feet (one meter)
away from another Ford Motor Company vehicle undergoing the TPMS
reset procedure at the same time.

•Do not wait more than two minutes between resetting each tire sensor
or the system will time-out and the entire procedure will have to be
repeated on all four wheels.
•A double horn chirp indicates the need to repeat the procedure.
TPMS reset procedure
Note:It is recommended that you read the entire procedure before
attempting.
Note:To enter the reset mode, Steps 1–6 MUST be completed within

7. Train the TPMS sensors in the tires using the following TPMS reset
sequence starting with theleft front tirein the following clockwise
order:
•Left front (Driver’s side front tire)
•Right front (Passenger’s side front tire)
•Right rear (Passenger’s side rear tire)
•Left rear (Driver’s side rear tire)
8.Left front tire:Place the TPMS reset tool against the left front tire
where the tire meets the rim, opposite from the valve stem (1) as shown.
This is where the sensor is located inside the rim.
Both tools, the TPMS training tool (part number 8C2Z-1A203-A)
or the Tire Pressure Monitor Activation Tool (part number
204-363), must be held against the tire sidewall opposite the
valve stem as illustrated. For the TPMS training tool, the device
should be held as illustrated, with the arrow on the tool pointing
towards the rim; do not use the tool with the arrow pointing away
from the rim as it may not activate the sensor.
9. Press and release the activation button while holding either tool to the
side wall until the horn sounds. The horn will sound once within
approximately 10 seconds to indicate the process was successful.
Note:
•If a double horn chirp is heard, repeat the procedure. If a single horn
chirp is not heard, move the vehicle to rotate the wheels at least a
14-turn and repeat the procedure starting with Step 1.
