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 displace-
ment connectors (e.g., 3M Scotchlock type connectors).
2. R
oute wiring using grommets and sealant when passing through compartment walls. Minimize the number of splices to reduce volt
-
age drop. High ambient temperatures (e.g., under-hood) will significantly reduce the current carrying capacity of wires, fuses, and
circuit breakers. All wiring should be protected from moving parts and hot surfaces. Looms, grommets, cable ties, and similar instal-
lation hardware should be used to anchor and protect all wiring.
3. F
uses 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.
General Wiring Instructions
Before attempting to connect the lightbar wiring harness, refer to the wiring diagram illustrated below. The wiring diagram describes the
function for each separate wire.
1. Route the lightbar power cable Red wire to a fused, ignition-switched power point. Connect the lightbar Black wire to a solid ground
connection on the vehicle (ideally, directly to the battery negative terminal). Use a fuse according to the wiring diagram. After the
lightbar has been mounted, route the control cable into the vehicle to the switch panel/controller location.
2. Connect the wires of the lightbar wiring harness to the switched side of each switch, or plug into optional controller. See the wiring
diagram for wire color/function legend.
3. Use cable ties and grommets to secure and protect all cables and wires.
