• Never attempt to install aftermarket equipment that connects to the vehicle
wiring without reviewing a vehicle wiring diagram available from the vehicle
manufacturer. Ensure that your installation will not affect vehicle operation
or mandated safety functions or circuits. Always check the vehicle for proper
operation after installation.
• Do not mount a radio antenna within 18 inches (45.7 cm) 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.
• Do not attempt to wash any unsealed electrical device while it is connected to its
power source.
During Installation and Service
• DO NOT get metal shavings inside the product. Metal shavings in the product
can cause the system to fail. If drilling must be done near the unit, place an ESD-
approved cover over the unit. Inspect the unit after mounting to be sure there are
no shavings present in or near the unit.
• DO NOT connect this system to the vehicle battery until ALL other electrical
connections are made, mounting of all components is complete, and you have
verified that no shorts exist. If the wiring is shorted to the vehicle body or frame,
high current conductors can cause hazardous sparks resulting in electrical fires or
flying molten metal.
• DO NOT install equipment or route wiring (or the plug-in cord) in the deployment
path of an airbag.
• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if the
seat needs to be recalibrated for proper airbag deployment.
• Before mounting any components, check the manual to be sure that the
component you are installing is suitable for use in that area of the vehicle. Many
components are not suitable for use in the engine compartment or other extreme
environmental exposure areas.
• When drilling into a vehicle structure, be sure that both sides of the surface are
clear of anything that could be damaged. Remove all burrs from drilled holes. To
prevent electrical shorts, grommet all drilled holes through which wiring passes.
Also, ensure that the mounting screws do not cause electrical or mechanical
damage to the vehicle.
• Refer to the manual packed with the lighting system for proper electrical
connections, additional precautions,and information.
• Because vehicle roof construction and driving conditions vary, do not drive a
vehicle with a magnetically mounted warning light installed. The light could fly
off the vehicle causing injury or damage. Repair of damage incurred because of
ignoring this warning shall be the sole responsibility of the user.
