This Remote Start/Alarm System is designed to be used with Automatic Transmission- Fuel Injection
Vehicles Only! The unit provides a selectable ignition control that allows a number of selectable timed outputs
for glow plug preheat in addition to a "Wait To Start Input" either of which may be required for certain diesel
vehicles, (see selectable feature #9 & or Green/Yellow Wire). If the diesel engine has a instant fire, (no glow
plug preheat system), feature #9 should remain in the default Gasoline mode setting. For diesel applica-
tions,consultyourdealerfor the type of ignition system used in your particular vehicle. Regardlessofthe
vehicle, Gasoline or Diesel, for every installation, the vehicle MUST HAVE a Tach Signal Input, Auto-
matic Transmission and Fuel Injection.
INSTALLATION OF THE MAJOR COMPONENTS:
CONTROLMODULE:
Selectamountinglocationinside the passenger compartment (up behind the dashboard). The mounting
location selected must be within 24" of the ignition switch wiring harness to allow connection of the 6 pin
mainwiringharness.
Becertainthatthechosenlocation willnot interferewithproper operationof thevehicle. Avoidmountingthe
moduleto or routingthewiring around thesteeringshaft/column, asthemodule or wiringmaywrap around
or block the steering wheel preventing proper control of the vehicle. Secure the module in the chosen
location using cable ties or screws as necessary.
Do Not Mount The Module In The Engine Compartment, as it is not waterproof.
SIREN:
Select a location in the engine compartment that is not accessible from below the vehicle. The selected
location must be clear of hot or moving parts within the engine compartment The siren must be pointed
downwardtopreventwaterretentionandtheflaredendmust be pointed away from and out of the engine
compartment for maximum sound distribution. Before securing the siren, check behind your chosen
location to assure that the mounting screws will not penetrate any factory wiring or fluid lines. Secure the
siren mounting bracket using #8 self taping screws or by first using the mounting bracket as a template,

HOODAND TRUNK PINSWITCHES:
The pin switches included in this package are intended for protecting the hood and trunk areas of the
vehicle. In all cases, the switch must be mounted to a grounded metal surface. When the pin switch is
activated,(hood/trunkopen), itwill supply a ground to the inputwireactivatingthealarm. In addition, the
hoodswitchis required for the safety shutdownoftheremote start unit. If the vehicle isbeingworkedon,
this hood switch prevents the remote start activation even if the RF command to start is issued. This
switch must be installed in all applications. Failure to do so may result in personal injury or
property damage. Mount the switches in the hood and trunk locations away from water drain paths. If
necessary, the included brackets may be used to move the switch away from rain gutters or allow
mounting to the firewall behind the hood seal. In both cases the switch must be set up to allow the hood
or trunk door to depress the switch at least 1/4 inch when the hood or trunk is closed and fully extended
when the hood or trunk is opened. For direct mounting, a 1/4 inch hole must be drilled. Carefully check
behindthe chosen locationtoinsure thedrillwill not penetrateanyexisting factorywiringor fluidlines. Drill
a 1/4" hole in the desired location and thread the pin switch into it using a 7/16" nut driver or deep well
socket. If using the mounting bracket, first secure the bracket to the desired location and secure the pin
switchinthe pre-threaded mounting bracket hole.
DASHMOUNTEDLED:
Thesmall LEDincluded in thekit willserve as a visualindicatorof the alarm's status andprovidea visual
deterrentto a potentialthief.The LEDalsoprovidesimportant feedbackinformation during thetransmitter
andfeature programmodes.The LEDshouldbe installedinthe dashin anareahighly visiblesothat itmay
be seen from the driver's seat as well as from outside the vehicle. Inspect behind the chosen location to
insure that the drill will not penetrate any existing factory wiring or fluid lines. Carefully drill a 1/4" hole in
the desired location and pass the connector end of the LED through the hole and toward the control
module. Press the LED firmly into place until it is fully seated in the mounting hole.
THERECEIVER/ANTENNAASSEMBLY:
The Superheterodyne ReceiverAntennaAssembly provided with this unit allows routing from below the
dashboard formaximum operatingrange. Choosea locationabove thebeltline (dashboard)of thevehicle
for best reception. Special considerations must be made for windshield glass as some newer vehicles
utilize a metallic shielded window glass that will inhibit or restrict RF reception. In these vehicles, route
theantennatowardarearwindowlocation for best reception. Secure the antenna with double stick tape
provided. Aftersecuring the antennawithtape,we advise also securing asectionoftheantenna cable to
afixed support. This willpreventthe antennafromdropping downincase the doublesticktape isexposed
to extreme heat which may loosen it's gummed surface. Route the connector toward the control module
using caution not to pinch the cable as this will cause poor or no RF reception to the control module.
VALET/PROGRAM/MANUALOVERRIDE SWITCH:
Select a mounting location that is easily accessible to the operator of the vehicle. It is not necessary to
conceal the switch. However, concealment is recommended as it offers a higher level of security. The
switchcanbe mounted to the lowerdashpanelin the driver's area. Inspect behindthechosenlocationto
insurethat adequateclearanceis allowedforthe bodyofthe switch,andalso thatthedrill willnot penetrate
any existing factory wiring or fluid lines. Drill a 9/32" hole in the desired location and mount the switch by
passingit through the panelfromtheunderside. Secure the switch using the nut, starwasher. Routethe
switch'sconnectortowardthecontrol module.
NOTE: During the program sequence, there are times when this switch and the ignition switch will be used
simultaneously. We recommend that the pushbutton switch be mounted on the left side of the ignition
switch to facilitate this operation.

CONTROLSWITCH:
Selectamounting location known andaccessibletothe operator of thevehicle. Alower dash panel,kick
panel,orglove box is desirable. Inspectbehindthechosen location to insurethatadequateclearance is
allowed for the body of the switch, and also that the drill will not penetrate any existing factory wiring or
fluid lines. Drill a 1/4" hole in the desired location and mount the switch by passing it through the panel
from the underside. Secure the switch using the nut, star washer, and on/off face plate. It is suggested
that the switch be oriented to allow the on position to be up toward the driver and the off position to be
downorawayfromthe driver. Routetheswitch'sconnectortoward the control module.
SHOCKSENSOR:
Select a centrally located, solid mounting surface for the shock sensor that will allow consistent opera-
tionfromallareas of the vehicle. The selected location must bewithin18"ofthecontrol module to allow
routing and connecting of the 4 pin harness. Secure the shock sensor to the chosen location using two
#8 self tapping sheet metal screws. The sensor can also be secured to an existing dash brace using
cable tie straps. Whichever mounting method is used be sure to allow access to the sensitivity adjust-
ment potentiometer for use later in the installation.
STARTER INHIBIT RELAY:
Select a mounting location within 12" of the ignition switch's low current start solenoid wire. Secure the
relay to an existing harness in the chosen location using a cable tie around the relay's wiring harness.
CAUTION! Donotwire tiethemetal brackettoan existingwiringharness asvibrationmay causechaffing
and shorting damaging the factory wiring. If an existing harness is not available then secure the relay's
metalmounting tabto an underdashmetalbracewith a #8selftapping sheet metalscrew. Wirethe relay
as per the diagram found later in this manual.
TheAX-900 is tobeusedin vehicles with AUTOMATIC TRANSMISSIONS only! Althoughthiscombina-
tionAlarm/Remote Start unit is a sophisticated system with many advanced features, IT MUST NOT be
installed into a vehicle with a manually operated transmission. Doing so may result in serious per-
sonalinjuryand property damage.

PURPLE Wire: Starter Output
Careful consideration for the connection of this wire must be made to prevent the vehicle from
starting while in gear. Understanding the difference between a mechanical and an electrical
Neutral Start Switch will allow you to properly identify the circuit and select the correct installa-
tion method. In addition you will realize why the connection of the safety wire is required for
all mechanical switch configurations.
Failureto make this connection properly can result in personal injury and propertydamage.
Inallinstallationsit is the responsibility of the installingtechniciantotestthe remote start unit and assure
that the vehicle cannot start via RF control in any gear selection other than park or neutral.
Inbothmechanical and electricalneutralstartswitchconfigurations,the connection of theYellowwirewill
bemadetothe low current start solenoid wire of theignitionswitchharness. Thiswirewill have +12 volts
when the ignition switch is turned to the start (crank) position only. This wire will have 0 volts in all other
ignition switch positions.
NOTE: This wire must be connected to the vehicle side of the starter cut relay (when used). For the
electrical neutral switch configuration, this connection must be made between the starter inhibit
relay, (when used) and the neutral safety switch as shown in the following diagram.
Failure to connect this wire to the ignition switch side of the of the neutral safety switch can result in
personalinjury and propertydamage.

Blue w/Black Trace Wire: Ignition 3 Output
Thiswireprovidesa 300mAground output that becomes active 3 secondsbeforetheRemoteStart Unit
initializes,andremainsgroundedwhilerunning plus an additional 4 seconds aftertheRemoteStartUnit
turns off. In all of the applications described below, a relay will be required.
This wire can be used to accommodate the following situations:
A. Shock Sensor By Pass:
If there is a Non Plug in Shock Sensor used with the alarm system and it is not shunted during the
RemoteStartactivationperiod,then vibrationfrom therunning vehiclecancausethealarmtotrigger. In
this case, connect the Blue/Black Wire to terminal #86 of a external relay. Connect terminal # 85 of
the relay to a fused + 12 volt battery source. Cut the shock sensor trigger wire and connect one end
of the cut wire to terminal #30 and the other end of the cut wire to terminal #87a. Just before the
Remote Start unit is activated, the relay contacts will open, preventing the shock sensor's operation
until the Remote Start unit shuts off.
B. Ignition 3 Output:
Somenewervehiclesusea third ignition wire which is required to start and keep the vehicle's engine
running. If this is the case, connect the Blue/Black wire to terminal #86 of an external relay. Connect
terminal # 30 & # 85 to a fused + 12 volt battery source rated for a minimum of 25 Amp. Connect
terminal # 87 to the third ignition wire in the vehicle.
C. GM VATS Key Override:
