INTRODUCTION

This installation manual guides you

through the steps you will take to in-

stall your alarm system. It includes a

checklist that keeps you on track and

a master wiring diagram that provides

an overview of the installation.

Plus, this manual has specific, de-

tailed instructions that tell you how to

first find connection points, and then

how to connect all wires.

Refer to the separate Operation Man-

ual to understand each of your

alarm’s features and to see how to

operate your alarm.

Since there are many different makes

and models of cars, it is impossible

for this manual to cover every wiring

configuration. Instead, this manual

gives you ways to determine the wir-

ing configuration for your vehicle

yourself.

We recommend you read through this

entire manual first to be sure there

will be no surprises during installa-

tion. We have included all the mount-

ing hardware you need for

installation. However, you need these

supplies. 

• 12-volt test light or volt meter

• Masking tape and a pen

• Wire Piercing Probe Adapters

(RadioShack Cat. No. 278-715)

In addition, it would be a good idea to

have the following on hand:

• Spare vehicle fuses

• Spare wire tap-ins and 14-gauge

hookup wire (in case a wire does

not reach where it needs to

reach), available at your local

RadioShack store

If you have trouble during installation,

help is just a toll-free call away. Call

the Auto Alarm Helpline anytime at:

1-800-598-2527

if you have any questions or prob-

lems.

Warnings: 

• This system produces extremely

loud (120 dB) alerts when trig-

gered. Extended, close-range

exposure to the siren can be

painful and might damage your

hearing.

• Allow at least 4 to 6 hours for a

complete installation. Be sure you

have all required supplies before

you begin. This installation could

require removing door panels and

dash access panels, and using a

test meter or test light to deter-

mine proper installation methods.
