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 (+) or positive side of the
battery, the alternator, or to the stud on the battery side of the starter solenoid. Use Table 2 for reference.
Table 1
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 instructions. Test the unit for
proper operation. Caution - Operating a siren
with a live speaker can inflict hearing damage--
always use hearing protection.

HEAD INSTALLATION - After installation of the lightbar, route the smaller of the two power cables through the
vehicle to the location chosen for the control head. Cut the cable to length and strip back the outer insulation
to expose the seven or eleven colored wires. Strip back 1/8” - 1/4” of colored insulation from each of the wires
in the cable. Connect these wires to the seven position / eleven position terminal plug enclosed in the user
parts bag, according to the diagram on the bottom of the control head.
