Wiring; Standard Wire Functions - Ecco 21 Series Installation And Operation Instructions Manual

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 specifications 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 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 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 the ArrowStik and Emergency Warning Flash modes.
• The WHT Drivers Side Cut wire may be changed to Arrowstik Flash. Please see the Arrowstik flash pattern section below for details.
