Wire Size and Termination
The adjacent wiring diagram shows the minimum wire size used for each
connection, along with recommended lead color. If the wire is longer than 10 ft. use
the next larger wire size. Use only high quality crimp connectors. Make sure all
connections are tight. Route wiring to prevent wear, overheating and interference
with air bag deployment. Use grommets and sealant when passing through
compartment walls. Minimize the number of splices to reduce voltage drop.
Ground connections should only be made to substantial chassis components,
preferably directly to the negative of the vehicle battery. Install and check all
wiring before connection to vehicle battery.
Wiring Connections:
BLACK LEAD: Connect the black wire from the amplifier to the negative side of the battery
or to a good chassis ground. Be sure to use minimum size #16 AWG.
RED LEAD: Connect the red wire from the amplifier to positive 12 VDC. It is strongly
recommended that you connect to a 12 VDC source that is present only when the vehicle
ignition is in the on position. A power relay may also be used. Be sure to use a minimum
size #16 AWG wire.
YELLOW LEAD: Connect to +12VDC through a switched power supply (possibly
ignition). This will turn the siren on and off. Be sure to use minimum size #18 AWG
wire.
ORANGE LEAD: This lead supplies power for the backlighting of the siren. Connect it
to +12VDC from the dash lights, parking lights or other switched source. Be sure to
use minimum size #18 AWG wire.
BROWN LEADS: Connect one lead to each terminal or lead of the speaker. Be sure to
use minimum size #16 AWG wire.
Optional Connections:
GREEN LEAD: Used for remote (Aux.) HORN control. Connect to horn ring
circuit or remote switch. Siren is shipped with positive voltage activation
defaulted (apply +12VDC for activation). For vehicles with negative activation
(connect to ground for activation), the unit must be opened up and have the Aux.
Horn polarity jumper switched. Refer to pages 3 & 4 for further details.
NOTE: Cut lead short if not used & insulate with electrical tape.
Testing - Test all siren functions after installation to assure proper operation. Test
vehicle operation to assure no damage to vehicle.
