Code 3 MX 7000 - Manual (Page 6)

WARNING!
!
Once the light bar is level and centered, mark the holes through the mounting tabs and remove the light bar from the vehicle.
Make sure that the drill will not damage anything when penetrating the roof. Drill the mounting holes and remove any burrs.
Attachment can be made using 1/4" cap screws, toggle bolts, or other fasteners as may be convenient. Use sealant as
necessary to prevent water leakage into the vehicle.

Before attempting to connect wiring refer to wire tag attached to the lightbar’s main cable. Each wire in the cable controls a separate
lightbar function as described in the wire tag.
The only significant difference between the MX 7000® with optional ArrowStik® and a conventional MX 7000, is the additional, thinner
cable exiting the bottom of the lightbar. The larger cable is the lightbar power cable. Route the wiring cable into the engine or
passenger compartment, taking care to use grommets and to apply sealant around openings to keep water out. It is advisable to
leave an extra loop of cable when installing the light bar to allow for future changes or reinstallations. Connect the black lead to a
solid frame ground (earth), preferably, the (-) or ground (earth) side of the battery and bring the other wires to the control heads or
switches. Connect the wires as directed by the wiring instructions on the cable.

Larger wires and tight connections will provide longer service life for components. For high
current wires it is highly recommended that terminal blocks or soldered connections be used
with shrink tubing to protect the connections. Do not use insulation displacement connectors
(e.g. 3M
® Scotchlock type connectors). Route wiring using grommets and sealant when
passing through compartment walls. Minimize the number of splices to reduce voltage drop.
High ambient temperatures (e.g. underhood) will significantly reduce the current carrying
capacity of wires, fuses, and circuit breakers. Use "SXL" type wire in engine compartment. All
wiring should conform to the minimum wire size and other recommendations of the
manufacturer and be protected from moving parts and hot surfaces. Looms, grommets, cable
ties, and similar installation hardware should be used to anchor and protect all wiring. Fuses or
circuit breakers should be located as close to the power takeoff points as possible and
properly sized to protect the wiring and devices. Particular attention should be paid to the
location and method of making electrical connections and splices to protect these points from
corrosion and loss of conductivity. Ground terminations should only be made to substantial
chassis components, preferably directly to the vehicle battery. The user should install a fuse
sized to approximately 125% of the maximum Amp capacity in the supply line to protect
against short circuits. For example, a 30 Amp fuse should carry a maximum of 24 Amps. DO
NOT USE 1/4" DIAMETER GLASS FUSES AS THEY ARE NOT SUITABLE FOR
CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS. Circuit breakers are very sensitive to high
temperatures and will "false trip" when mounted in hot environments or operated close to their
capacity.
