TR Series Wiring
A TR series lightbar has a single cable with 11 colored wires. A dedicated ground wire, a dedicated power wire and five colored control
wires run through the main driver board and the 4 additional wires supply (+) power directly to any additional modules such as Work
Lights, Alley Lights, Take Downs or Stop/Turn/Tail (STT) modules.
The 16 AWG black ground wire should be connected directly to the battery. The 16 AWG red power wire requires a constant 10 to 16V
power source with a customer supplied in line 15A fuse.
The five control cable wires (listed in TABLE 15 below) routed through the driver board carry only low current (30 mA average) input
signals to control the light bar 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
configuration specific functions of each wire. Use appropriate high-temperature wiring if it passes through the engine compartment. Use
cable ties and grommets to secure and protect all cables and wires.

TABLE 16
To change a flash pattern on a single emergency level mode:
1. Power-up the Lightbar and apply +power to the level mode wire(s) you wish to change (see TABLE 16). The lightbar will flash the
default pattern.
2. Momentarily touch the GRN pattern select wire to (+) power to cycle through to the next flash pattern shown on TABLE 17.
3. To reset the flash pattern to the factory default, hold the GRN pattern select wire to (+) power for ~5 seconds.
