Please follow these guidelines when wiring the siren: 

 

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 wh en 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. 

 

Siren

 

Wiring Connections:  

 

Siren input and output 
connections are made on the 
back of the unit through a 
12-pin connector and wiring 
harness (part # SWH-48). 

 

Please review the Siren Wiring diagram on

 page 8

 and make your connections 

as follows: 

 

 

BLACK

:   (Pins 2 & 5)

 

Ground

 - Connect these leads to the negative of the 

battery, or to a good chassis ground.  You MUST connect both 
leads if you are using two 100-watt speakers.  Be sure to use 
minimum size #14 AWG w ire. 

 

RED

:   (Pins 1 & 4)

 

Power

 - Connect both leads to the positive side of the 

battery, or to a high current power buss.  You MUST connect both 
leads if you are using two 100-watt speakers.  A power relay may 
also be used.  Be sure to use minimum size #14 AWG wire. 

 

YELLOW

:   (Pin 11)

 

Ignition Switched Power

 - Connect to +12VDC through 

a switched power supply (possibly ignition).  This will turn the 
siren and light controls on and off.  Be sure to use minimum size 
#18 AWG wire.  

NOTE:

 This wire performs the same function as 

the On/Off switch on the front of the unit.

 

 

ORANGE

:   (Pin 9)

 

Backlight Power

 - This lead supplies power for the 

backlighting of the faceplate.  Connect it to +12VDC from the 
dash lights, parking lights or other switched source.  Be sure to use 
minimum size #18 AWG wire.  

Note: The unit will still function 

without power to this wire.  There will not be any backlighting or 
visual feedback on the switches though.

 

 

BROWN

:   (Pins 7 & 12)

 

Speaker Output

 - Connect one lead to each terminal 

or lead of the speaker.  Be sure to use minimum size #14 AWG 
wire.  

If connecting a second speaker in parallel, you must 

observe the polarity of the speakers (phasing).  Be sure that the 
positive terminals of both speakers are connected together to the 

same

 brown wire from the siren.

  In which case, the negative 

terminals of both speakers would also be connected together to the 
other brown wire.
