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.
