6. To make wiring easier, remove the seats, spare tire, and pull down the headliner
where needed.
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 in (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.
11. After drilling holes for wires, de-burr them, smooth sharp edges, and insert grommets
to protect the wires from chafing.
12. When you frame ground the equipment, use the manufacturer-supplied ground
locations in the vehicle. Ensure that the location is free of paint, dirt, and other
contaminants.
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 allow
disconnection on 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 can cause serious injury or death.
