Wiring the Allegiant Light Bar
7. Separate all electronic equipment wiring from two-way radio equipment wiring.
8. To avoid interference, keep two-way radio antennas a minimum of 18 inches (45.7
cm) away from warning equipment.
9. Whenever possible, run full wire lengths. DO NOT splice the wires.
10. Do not coil excess wire. Leave a drain loop for servicing.
DRILLING PRECAUTIONS: Before drilling holes, check the area into which
you plan to drill to ensure that you do not damage vehicle components. All
drilled holes should be deburred and all sharp edges should be smoothed.
Additionally, all exterior drilled holes must be sealed with Motorcraft seam
sealer T-A-2-B or equivalent to prevent the potential exposure to carbon
monoxide or other potentially harmful fumes. Failure to observe this warning
could cause serious injury or death.
11. When you frame-ground the equipment, use the manufacturer-supplied ground
locations in the vehicle.
IMPORTANT: After the installation, frequently inspect the light bar and mounting feet
to ensure that all fasteners and brackets are tight.
Connecting Power to the Light Bar
NOTE: Plan the location of the wire-routing hole in the vehicle roof so that the power
and communication cables do not have tight bends and have some slack to ease
removal.
BATTERY EXPLOSION: To avoid a battery explosion, always disconnect the
negative battery cable first and reconnect it last. Avoid causing a spark when
connecting near or to the battery. The gases produced by a battery can cause
a battery explosion that could result in vehicle damage and serious injury.
SEAT REMOVAL PRECAUTION: If a vehicle seat is temporarily removed, verify
with the vehicle manufacturer if the seat needs to be recalibrated for proper
airbag deployment. Failure to follow this warning cause serious injury or
death.
REVERSE POLARITY / MISWIRING: Reverse polarity or incorrect voltage may
damage the light. To avoid damage to the light, ensure that the battery voltage
is the same as the voltage rating of the light and that the correct polarity
is observed. If you are connecting to a cigarette lighter plug or 12 V outlet,
connect the positive wire to the center terminal and connect the negative wire
to the outer terminal.
