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 displace-
ment 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 compo-
nents, 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.

WARNING!

Retrofit existing lightbars with wiring for the LIT3 Mounting Kit lighted version

Step 1 Mark the location for the Mounting Kit wire grommet's two holes near the center and 9 1/2" from each end of the lightbar's frame. A flat
area is needed that is 1/2" in diameter minimum to accept a 3/8" diameter hole. (see Figures 49 and 50).

Step 2 Drill a 3/8" diameter hole at the two locations for the Mounting Kit wire grommet. (see Figure 51).

Step 3 Feed the two terminals with the round plastic sleeve through the 3/8" hole from the internal side of the Lightbar and pull the wires to pop
the grommet into the hole (see Figure 52)
Note: It is helpful to use a blunt tool to gently push the Grommet into the hole so that the
sealing groove pops into the frame hole.

Step 4 Connect the quick slides to the desired wires inside the light bar (see page 6 for light bar internal wiring connection instructions) and follow
the installation instructions starting at page 3 of this manual.

LED Fusing Considerations

Although the average current draw per module is very low, due to the type of circuit used to power each
module, the instantaneous peak current to a module can be significantly higher during low voltage
conditions. To avoid prematurely blowing ATO style fuses or tripping breakers it is recommended the
following rule-of-thumb be used to size fuses or breakers. This is especially important in lightbars with
many LED modules running off a single fused source.

Minimum fuse size calculation:

For LED 12 volt electrical current
1.5 x (number of modules being fused)
Example:

2 intersection modules and 6 directional modules.
Minimum fuse requirement for single fuse - 1.5 (8) = 12 A
