Wiring Instructions
Route the wiring cable into the engine or passenger compartment, taking care to use grommets and `
to apply sealant around openings to keep water out. It is advisable to leave an extra loop of cable
when installing the light bar to allow for future changes or reinstallations. Connect the black lead to a
solid frame ground (earth), preferably the (-) or ground (earth) side of the battery and bring the other
wires to the control head or switches. Connect the wires to the control head or switch (as directed by
the wiring instructions on the cable). Next, calculate the light bar power draw. Table 1 consists of an
equation and data for quick calculating of light bar load. Run a power wire from the control head to
the (+) positive side of the battery, the alternator, or the stud on the battery side of the starter sole
noid. Use Table 2 for reference. Speaker Wires: If the light bar has a speaker section, the blue wires
go to the siren amplifier and are to be connected in accordance with the siren manufacturer’s instruc
tions. Test the unit for proper operation. CAUTION: Operating a siren with a live speaker can inflict
hearing damage -- always use hearing protection.
!
WARNING!
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 displacement
connectors (e.g. 3M
® Scotchlock type connectors). Route wiring using grommets and
sealant when passing through compartment walls. Minimize the number of splices to
reduce voltage drop. High ambient temperatures (e.g. underhood) will significantly reduce
the current carrying capacity of wires, fuses, and circuit breakers. Use "SXL" type wire in
engine compartment. All wiring should conform to the minimum wire size and other
recommendations of the manufacturer and be protected from moving parts and hot
surfaces. Looms, grommets, cable ties, and similar installation hardware should be used to
anchor and protect all wiring.
Fuses or circuit breakers should be located as close to the power takeoff points as possible
and properly sized to protect the wiring and devices.
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.
Ground terminations should only be made to substantial chassis components, preferably
directly to the vehicle battery.
The user should install a fuse sized to approximately 125% of the maximum Amp capacity
in the supply line to protect against short circuits. For example, a 30 Amp fuse should
carry a maximum of 24 Amps. DO NOT USE 1/4" DIAMETER GLASS FUSES AS THEY
ARE NOT SUITABLE FOR CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS. Circuit
breakers are very sensitive to high temperatures and will "false trip" when mounted in hot
environments or operated close to their capacity.
Remounting
When moving an LP 6000 bar from one vehicle to another, we suggest that new 5/16" mounting bolts
and rubber feet be used. These are standard hardware items that can usually be found at any hardware
store, or they can be ordered from the factory. The special hooks are stainless steel and should be
saved and reused.
NOTE! If different holes must be used to mount the brackets, tape over the unusual holes with duct
tape on the inside to prevent dirt and water from entering the light bar.
