2010 Mercury Grand Marquis AUX

CENTER CONSOLE (IF EQUIPPED)
Your vehicle may be equipped with a variety of console features. These
include:
•Utility compartment
•Power point (inside storage bin)
•Cupholders
•Air vents to the rear seating positions (heat only)
WARNING:Use only soft cups in the cupholder. Hard objects
can injure you in a collision.
AUXILIARY POWER POINT (12VDC)
Power outlets are designed for accessory plugs only. Do not insert
any other object in the power outlet as this will damage the
outlet and blow the fuse. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
The auxiliary power point is located under the cup holder and ashtray
drawer in the center stack. The auxiliary power point for five passenger
vehicles is located in the floor console storage bin.
Do not use the power point for operating the cigarette lighter element (if
equipped).
To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12 VDC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer toFuses and
relaysin theRoadside Emergencieschapter for information on
checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
•do not use the power point longer than necessary when the engine is
not running,
•do not leave battery chargers, video game adapters, computers and
other devices plugged in overnight or when the vehicle is parked for
extended periods.
Always keep the power point caps closed when not being used.

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
protects 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.
