Wiring the Allegiant Light Bar
Wiring the Allegiant Light Bar
Before proceeding, ensure that the light bar has been installed on the vehicle roof
in accordance with the instructions included with the mounting kit. Depending on
the type of vehicle and mounting system feature, there are two options available
for installing the light bar to the roof of the vehicle: hook-on mounting or permanent
mounting.
INSTALLATION PRECAUTION: Do not mount a radio antenna within 18 inches
of the lighting system. Placing the antenna too close to the lighting system
could cause the lighting system to malfunction or be damaged by strong radio
fields. Mounting the antenna too close to the lighting system may also cause
the radio noise emitted from the lighting system to interfere with the reception
of the radio transmitter and reduce radio reception.
Planning the Electrical Installation
The light bar is completely wired at the factory and does not require any additional
internal wiring. All the conductors necessary for control of any and all basic and
optional functions are contained in the nine-conductor cable. The basic light functions
of the Allegiant
®
must be controlled by
appropriately rated switches.
To prevent damage to the light bar and vehicle and ensure that all equipment
operates properly, carefully plan where to mount and wire the light bar and controlling
equipment:
1.
Verify that the light bar and mounting hardware fit the vehicle.
2.
Determine where to mount the light bar on the vehicle.
3.
Determine where to mount the controlling equipment:
• Trunk or remote location
• Console
AIRBAG DEPLOYMENT: Do not install equipment or route wiring in the
deployment path of an airbag. Failure to observe this warning will reduce the
effectiveness of the airbag or potentially dislodge the equipment, causing
serious injury or death.
4.
Decide where to route wiring around airbag areas.
5.
Decide where to route the light bar power and ground wires.
6.
To make wiring easier, remove the seats and spare tire and pull down the
headliner where needed.
7.
Separate all electronic equipment wiring from two-way radio equipment wiring.
