IF Series Wiring
An IF series lightbar has a dedicated ground wire and one or more +power wires routed to the modules. The black ground wire should be
connected directly to the battery. The amp ratings for each module type are detailed in the specifications section of this installation guide.
Before attempting to connect the lightbar wiring harness, refer to the configuration specific wiring key included with the lightbar for the func-
tions 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.
IF Series Flash Pattern Selection
The flash pattern on corner and directional modules can be cycled to the next flash pattern on each individual module by momentarily short-
ing together the JP1 pins with a wire or the blade of a screwdriver (shown below). The light head will reset to the default flash pattern when
the JP1 pins are shorted together for 5 seconds or more and then releasing. Module pairs connected by a sync wire must be individually set
to the same flash pattern to properly synchronize.
