CC Series Wiring
A CC series lightbar has a 2-wire power cable and a 16-wire control cable. The entire power load of the bar goes through the power cable.
The black ground wire should be connected directly to the battery. The 10 AWG red power wire requires a constant 10 to 16V power source
with a customer supplied in line fuse. To select an appropriately rated ATO (regular) or Maxi Fuse, add the amp ratings, found in the speci-
fications section, of the modules in your configuration specific lightbar and based on that sum, insert a fuse of the next larger size (to be no
larger than a 30 A fuse). The 16 control cable wires carry only low power (30 mA average) input signals to control the lightbar functions and
must be routed to the output of a control switch (or directly to multiple switches).
Before attempting to connect the lightbar wiring harness, refer to the configuration specific wiring key included with the lightbar for the con-
figuration specific functions of each wire. Use an appropriate high-temperature wiring if it passes through the engine compartment. Use cable
ties and grommets to secure and protect all cables and wires.

Note:
-When the Arrowstik Left and Arrowstik Right wires are both connected to +power, the Center-Out Arrowstik function is activated.
-The Front Cut and Rear Cut functions must be used with the greatest care to ensure that the use of these functions do not diminish
the effectiveness of the Emergency Warning signal.
-When the Pattern Select wire is connected to +power alone, test mode is enabled to exercise all outputs in sequence.
-The Dim Function lowers the brightness of the LEDs in both the ArrowStik mode and Emergency Warning Flash modes.
-The WHT Drivers Side Cut wire may be changed to Arrowstik Flash. Please see the Arrowstik flash pattern selection section below
for details.
-Lightbars equipped with a DOT strip assembly are wired in conjunction with the STT tail light function. All STT functions are
powered independent of the central driver PCA.
Emergency Mode Flash Pattern Selection
There are seven customizable emergency flash pattern modes available based on the wire combinations shown in TABLE 3. When using
individual switches, make sure to configure all possible switch combinations. The default setting is unsynchronized which allows each light
head module group to be configured separately and the lightbar to flash in an unsynchronized pattern. Steps to synchronize the light head
module groups together are detailed in later sections.
