HARNESS WIRE INFORMATION Fig. 2
8. The wire harness provided with the siren
has a male plug end that mates with
the connector located in the back of the
siren controller. The plug is designed to
connect and lock only in one position.
WARNING
• Do not connect the wire harness plug to the
siren controller until all connections have
been completed, wires are secured and the
installer inspects and verifies that no short
circuits exist.
• Before wiring the siren controller to the vehicle, carefully review the vehicle’s shop or build manual to ensure
the connection points will not affect the circuit or the vehicle’s operation.
• If the vehicle is equipped with air bags, the installer MUST consult the vehicle’s shop or build manual to ensure
that the siren’s harness wires will not affect deployment of the air bags. If necessary consult manufacturer for
their recommendation.
• Any wires that pass through the vehicle’s firewall or drilled sheet metal must have a rubber grommet or approved
insulator inserted into the hole to protect the wires from being shorted or damaged from rough edges.
• Failure to follow these instructions could cause hazardous sparks, electrical fire, burns and personal injury.
HARNESS WIRING
9. BROWN WIRES are connected to speaker. If the harness wires need to be extended, use 18 gauge or
heavier wire.
10. BLACK WIRE is connected to ground. Secure black wire under a metal body bolt in the dashboard area;
make sure that the METAL surface around the bolt is clean of rust and paint to make a good electrical
connection.
11. REd WIRE is connected to the vehicle’s fuse-block or under dash wire that can provide
+12-volts. The red wire is provided with an in-line fuse, that must be used. The fuse must not
be more than 10” from the power source. (Note: if you need to replace the fuse use a 15 amp.)
IMPORTANT: Carefully review the vehicle’s shop or build manual to ensure that the +12-volt electrical
connection point will not affect the circuit or the vehicle’s operation.
NOTE: Tape all connections and secure wires.
12. Connect the wire harness male plug to its female mate in the rear of the siren controller. Note: The plug is
designed to connect and lock only in one position.
NOTE: The siren’s controller electronic circuit is fuse protected. The fuse can
be accessed at the rear of the siren controller. Replacement fuse is 15 amp
type SFE.
