IMPORTANT! Read all instructions before installing and using. Installer: This manual must be
delivered to the end user. This manual assumes installation by a suitably qualied Automotive Technician.
ECCO 21 Series Lightbars are versatile and powerful warning devices that offer numerous lighting module and length options. The 21
Series is suitable for many vehicle applications and features a durable aluminum chassis, polycarbonate lenses and a sleek, low prole
design. These lightbars can either be mounted permanently to the vehicle or using an optional, semi-permanent roof mounting kit. There
are two types of 21 Series lightbar - IF (independent ashing) and CC (centrally controlled). IF (Independent Flashing) indicates the
lightbars modules have individual electronic circuits that control their operation, each module, a group or a pair of modules can be controlled
independently. CC (Centrally Controlled) indicates the lightbar’s modules are controlled by a centralized electronic driver board which
provides simpler and greater programming exibility of all lightbar functionality.
Unpacking and Pre-Installation:
Carefully remove the lightbar and place it on a at surface. Examine the unit for transit damage and locate all parts. If damage is found or
parts are missing, contact the transit company or ECCO. Do not use damaged or broken parts.
Ensure the lightbar voltage is compatible with the planned installation.

Notes:
1. 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).
2. 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., under-hood) will signicantly reduce the current carrying capacity of wires, fuses, and
circuit breakers. 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.
3. 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.
4. 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.
5. Ground termination should only be made to substantial chassis components, preferably directly to the vehicle battery.
6. Circuit breakers are very sensitive to high temperatures and will “false trip” when mounted in hot environments or operated close to
their capacity.
Important!
This unit is a safety device and it must be connected to its own separate, fused power point to assure its continued operation should any
other electrical accessory fail. Do not wire in parallel with any other accessory.
Wiring Instructions:
Caution:
Disconnect the battery before wiring up the lightbar, to prevent accidental shorting, arcing and/or electrical shock.
!
1. Loosen the 5/16” nuts to allow the mounting feet to slide along the base of the lightbar. Loosely attach the mounting strap to each foot
using the supplied pan head phillips screws and lock washers.
2. Center the lightbar across the vehicle and align the strap mount brackets to hook into the gutter of the vehicles door frame as shown in
FIGURE 6.
3. Secure the feet to the lightbar in location by tightening the four nuts on each foot.
4. Slowly tighten the pan head screws to secure the strap mount brackets to the lightbar feet and around the door gutters, keeping the
lightbar centered and level. Ensure the doors close completely and secure each strap mount bracket to the door frame. Mounting
geometry and parts will vary for different vehicles. See the Wiring section of this manual for further wiring instructions.

Wiring
A multicolor LED 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cations section, of the modules in your conguration specic 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 func-
tions 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 conguration specic wiring key included with the lightbar for the con-
guration specic 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 the ArrowStik and Emergency Warning Flash modes.
• The WHT Drivers Side Cut wire may be changed to Arrowstik Flash. Please see the Arrowstik ash pattern section below for details.
