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.

3.Ammunition –The safest location for ammunition is the forward
package shelf and on the side shelves. It is recommended that a plastic
storage container be utilized and mounted using theTrunk Mounting
Equipment Guidefor proper fastener locations. It is also recommended
that ammunition remain in the purchased container and be placed in a
safe storage container.
Low risk items –These items are soft in feel and pose a low risk of
trunk wall, rear seat area, and fuel tank puncture. Examples are: a soft
camera case, biohazard kit in plastic boxes, gloves, safety rope, tow
strap, traffic cones & sleeves, rain gear, riot gear (soft), emergency
blankets, bullet resistant vest, tie straps, cloth tape, garment bags, first
responder kit, Res-Q-Flo mask (placed in garment bag), fuses (plastic
container), briefcase, notebooks, spray bottles, helmet, and jumper
cables. It is not essential but recommended that the Trunk Pack™ can
be considered for organization of low risk items, especially if mixed with
“Carry With Caution”items.
BODY
Fire suppression system (if equipped)
Your vehicle may be equipped with an optional fire suppression system.
The fire suppression system is designed to help reduce the risk of injury
in high-speed rear impacts. The fire suppression system deploys
chemicals designed to slow the spread of fire or potentially extinguish a
fire, thereby providing more time for occupants to escape from a crashed
vehicle.
The fire suppression system is mounted beneath the vehicle and
attached to the frame above and forward of the fuel tank and rear axle.
The fire system control module is mounted inside the passenger
compartment centered underneath the rear seat cushion. The system is
designed to deploy automatically after sensing a high-speed/high-energy
rear end impact.
There is a covered manual activation switch mounted in a console on the
headliner between the visors that can be used by vehicle occupants to
manually deploy the system. The fire suppression system can be
manually deployed any time the key or engine is turned on by pushing
the button underneath the cover. The button can be accessed three
ways:
1. Pushing on the cover will release the cover latch, allowing the door to
swing open and expose the button;
2. The cover can be pulled open;
