Power and Ground Wiring Connections
Please review pages 39-43 to determine the minimum wire size used for each connection.
We have enclosed a wiring harness for the Power, Ground, and AUDIO I/O wires that can be
used for most applications. Recommended wire colors are listed next to each function.
Please also use the following guidelines when wiring your siren:

Use only high quality crimp connectors.

Make sure all connections are tight.

Route the wiring to prevent wear, overheating, and/or 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 can be made to substantial chassis components, but preferably
directly to the negative of the vehicle battery.

Install and check all wiring before connection to vehicle battery.
Power (+12VDC) and ground connections are made through
several terminal blocks on the back of the siren.
Ground: (Black) Make your ground connection using the
BLACK 8 AWG wire to the single terminal shown to
the right.
Power: (Red) C12VDC to BOTH power terminals on the left side of the rear of the
unit. Use 8 AWG wires for these connections. The power supply for this unit must
be capable of delivering peak currents
up to 150 amps for adequate short circuit
protection and reliable operation (50 amps for the audio functions and up to 100
amps for the additional devices and/or lights you have connected to the outputs).
The preferred source is directly at the vehicle battery. Review the chart below for
proper Power and Ground wire sizes.
Electrical connections to the unit are made using several terminals and removable
connectors located on both the front and back of the unit. The unit is protected by a 20 amp
fuse on the input power and each output is protected by a 20 amp fuse. Wiring diagrams on
pages 41 and 44 show detail of how to make all of the necessary electrical connections.

* We recommend running the enclosed 8 AWG power wires to a power distribution block
located near the siren. Then use two 6 AWG wires for the run to the battery.
