Wiring Instructions
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.
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 pass-
ing 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 pro-
tected 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.

routing
The only significant difference between the 21IF™ with optional ArrowStik ® and a conventional 21IF™ 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 head or switches. Connect the wires as directed by the wiring instructions on the cable.

OPTIOnAL L.E.D. nArrOWSTIK® (11-wire) WIrIng AnD COnTrOL HEAD InSTALLATIOn - After installation of the
lightbar, route the smaller of the two power cables through the vehicle to the location chosen for the control head. Cut the
cable to length and strip back the outer insulation to expose the seven or eleven colored wires. Strip back 1/8” - 1/4” of
colored insulation from each of the wires in the cable. Connect these wires to the seven position / eleven position terminal
plug enclosed in the user parts bag, according to the diagram on the bottom of the control head.
refer to the control head manual packaged with the lightbar for control head installation
and operation instruction.
