CAUTION!
Disable power before wiring up the beacon/strobe
head, to prevent accidental shorting, arcing, and
electrical shock.
Important!
This system must be connected to a
separate, fused power point. Do not wire in parallel
with any other accessory.
Gerneral Wiring Instructions:
1. Route 14AWG or larger wires from the vehicle positive (battery,
alternator, fuse block) to the switch panel in the cab. Use high-
temperature wire if it passes through the engine compartment.
Install an inline fuse close to the power take-off point. For each
circuit, use a fuse according to the following tables:
2. Connect the power wires to the positive side of the appropriate
lightbar switch or switches of the switch panel with quick
disconnect terminals or by soldering.
3. After the light bar has been mounted, route the lightbar cable
into the vehicle to the switch panel location
4. Connect the 16 AWG wires (14 AWG on the 2-Con
Ground System) of the lightbar cable to the switched side of
each switch. See the tables below for wire color / function
legend. Your bar may not be equipped with all of these functions;
unused wires may be trimmed flush with cable end.
5. Connect the lightbar cable ground wire to a solid ground
connection on the vehicle. If this wire needs to be lengthened,
use a 10AWG or larger White wire.
6. Use cable ties to secure all cables and wires.
