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.

Aftermarket equipment installation
Ford has developed aPolice Interceptor Modifier Guideto assist the
vehicle modifier in safely installing police equipment into the vehicle.
The guide provides detailed information on the location of key vehicle
components that must be untouched and warnings for other areas where
caution must be exercised. The Modifier Guide is available for
downloading, free of charge, from www.fleet.ford.com.
When installing aftermarket equipment, avoid using fasteners that are too
long for the application or are in an area which might damage vehicle
components, including wiring, brake lines, fuel tank and lines, powertrain
components, exhaust system and suspension.
Also, do not make electrical connections to vehicle electrical systems not
specifically designed for aftermarket equipment installations. Refer to the
“Wiring Diagram Manual” for electrical system information.
Do not install any components into the powertrain control module
(PCM) or PCM harness. Connecting into this system may affect engine
and transmission operation.
As an example: connection of aftermarket electrical equipment into the
brake light circuit or any other circuit which is connected to the PCM,
anti-lock brake computer, airbag system or any other vehicle system
which will cause vehicle malfunction.
WARNING:Contact during a crash with aftermarket equipment
in a vehicle can result in a personal injury.
WARNING:Installation of prisoner barriers may increase the
risk of injury to front seat occupants if the vehicle is impacted
from the rear at high speeds. This risk should be balanced, by the law
enforcement agency, against the risk of injury to the Officer associated
with prisoner transport.
Trunk Pack™ and trunk loading
WARNING:Ford recommends that police equipment be both
secured and laterally aligned. Hard, stiff or sharp objects,
especially when not secured or properly located, pose a risk to the fuel
tank and back seat occupants in the event of a high speed rear impact.
After-market organizers that do not adequately deform in rear-impacts
can themselves become injury-producing objects. When locating,
securing and mounting police equipment, please review theTrunk
Equipment Mounting Guide,available on the www.cvpi.com website,
which provides recommended fastener mounting types and locations.
