The AA-RS20CS Remote Start/Alarm System is designed to be used with Automatic Transmission Vehicles Only! The unit provides no output for glow plug pre-heat and may not be desirable for diesel vehicles. If the diesel engine has a instant fire, (no glow plug pre-heat system), a tach signal input, and an Automatic Transmission, this unit may be used. For diesel applications, consult your dealer for the type of ignition system in your particular vehicle.

INSTALLATION OF THE MAJOR COMPONENTS:

CONTROL MODULE:

Select a mounting location inside 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 main wiring harness. Be certain that the chosen location will not interfere with proper operation of the vehicle. Avoid mounting the module to or routing the wiring around the steering shaft/column, as the module or wiring may wrap 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 downward to prevent water retention and the flared end must 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, scribe or mark the three bracket mounting holes. Drill the three marked holes using a 1/8" drill bit, than mount the siren using #8 sheet metal screws.

HOOD AND TRUNK PIN SWITCHES:

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/trunk open), it will supply a ground to the input wire activating the alarm. In addition, the hood switch is required for the safety shut down of the remote start unit. If the vehicle is being worked on, 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 behind the chosen location to insure the drill will not penetrate any existing factory wiring or fluid lines. 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 switch in the prethreaded mounting bracket hole.

DASH MOUNTED L.E.D.:

The small Red LED included in the kit will serve as a visual indicator of the alarm's status and provide a visual deterrent to a potential thief. The LED also provides important feed back information during the transmitter and feature program modes. The LED should be installed in the dash in an area highly visible so that it may 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.

THE RANGE EXTENDER ANTENNA:

The range extender antenna provided with this unit allows routing from below the dash board for maximum operating range. Choose a location above the belt line (dashboard) of the vehicle 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 the exposed, (non shielded) end toward a rear window location for best reception. Secure the exposed end with double stick tape or instant stick glue. After securing the exposed end of the antenna with the tape or glue, we advise also securing a section of the antenna cable to a fixed support. This will prevent the antenna from dropping down in case the double stick tape is exposed to extreme heat which may loosen it's gummed surface.

VALET/PROGRAM/MANUAL OVERRIDE 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 switch can be mounted to the lower dash panel in the drivers area. Inspect behind the chosen location to insure that adequate clearance 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 down or away from the driver . Route the switch's connector toward the control module .

CONTROL SWITCH:

Select a mounting location known and accessible to the operator of the vehicle. A lower dash panel, kick panel, or glove box is desirable. Inspect behind the chosen location to insure that adequate clearance 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 down or away from the driver. Route the switch's connector toward the control module. Place the RED rubber boot, included in the kit, over the switch handle to differentiate this switch from the valet/program switch.

SHOCK SENSOR:

Select a centrally located, solid mounting surface for the shock sensor that will allow consistent operation from all areas of the vehicle. The selected location must be within 18" of the control module to allow routing and connecting of the 4 pin harness. Secure the shock sensor to the chosen location using two #8 self taping 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 adjustment 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! Do not wire tie the metal bracket to an existing wiring harness as vibration may cause chaffing

and shorting damaging the factory wiring. If an existing harness is not available then secure the relay's metal mounting tab to an under dash metal brace with a #8 self taping sheet metal screw.

Wire the relay as per the diagram found later in this manual. The AA-RS20CS is to be used in vehicles with AUTOMATIC TRANSMISSIONS only! Although this combination Alarm/Remote Start unit is a sophisticated system with many advanced features, IT MUST NOT be installed into a vehicle with a manual operated transmission. Doing so may result in serious personal injury and property damage.

IMPORTANT!

DO NOT PLUG THE SIX PIN MAIN POWER HARNESS OR THE MUL TI PIN INPUT / OUTPUT HARNESS INTO THE CONTROL MODULE UNTIL ALL CONNECTIONS TO THE VEHICLE HAVE BEEN MADE. AFTER SELECTING YOUR TARGET WIRES AS DEFINED BELOW, DISCONNECT TH E NEGATIVE BATTERY CABLE FROM THE VEHICLE BATTERY PRIOR TO MAKING ANY CONNECTIONS.

WIRING THE 6 PIN MAIN POWER HARNESS: RED w/ WHITE Trace Wire: + 12 volts Battery 1 Source

Connect this wire to a + 12 VDC constant source found at the vehicle's ignition switch using the 30 Amp fuse and holder provided.

RED Wire: + 12 Volts Battery 2 Source Connect this wire to a + 12 VDC constant source found at the vehicle's ignition switch using the 30 Amp fuse and holder provided, but NOT the same vehicle wire as used by the battery 1 source. Most vehicles have more than one battery source supplying power to the ignition switch. Separate feed wires must be used for the Red and Red/White wires. If your vehicle does not have two battery feed wires at the ignition switch then it is possible to connect both wires to the vehicle's battery.

IMPORTANT!

It is the responsibility of the installing technician to determine the load factor of the vehicles electrical circuits when the vehicle is running and to adequately fuse the two power wires based on that load. If the vehicle, running under load with the air conditioner, heater blower motor , and accessories exceed 24 Amps continuous, we recommend that two fuses be used in combination on each power wire as shown below. For additional information see Tech Update issued 9/30/96.

YELLOW 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 installation method. In addition you will realize why the connection of the safety wire is required for all mechanical switch configurations.

Failure to make this connection properly can result in personal injury and property damage. In all installations it is the responsibility of the installing technician to test the remote start unit and assure that the vehicle cannot start via RF control in any gear selection other than park or neutral. In both mechanical and electrical neutral start switch configurations, the connection of the Y ellow wire will be made to the low current start solenoid wire of the ignition switch harness. This wire will 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 personal injury and property damage. SEE NEUTRAL START SAFETY TEST FOR FURTHER DETAILS. BLUE Wire: Ignition 1 Output Connect this wire to the ignition 1 wire from the ignition switch. This wire will show +12 volts when the ignition key is turned to the to the "ON" or "RUN" and the "START" or CRANK" positions, and will have 0 volts when the key is turned to the "OFF" and "ACCESSORY" positions.

YELLOW START WIRE DETAIL

GREEN Wire: Ignition 2 Output

Connect this wire to the ignition 2 wire from the ignition switch. This wire will show + 12 volts when the ignition key is turned to the "ON" or "RUN" position and is some cases the "ST ART" or CRANK" position. This wire will show 0 volts when the key is turned to the "OFF" and "ACCESSORY" positions.

VIOLET Wire: Accessory Output Connect this wire to the Accessory wire from the ignition switch. This wire will show + 12 volts when the ignition switch is turned to the "ACCESSORY" or "ON" and "RUN" positions, and will show 0 volts when the key is turned to the "OFF" and "START" or "CRANK" positions.

WIRING CONNECTIONS: Multi Pin Accessory Input/Output Harness

White w/ Red Trace Wire: Parking Light Flasher Feed

This wire is the common contact of the on board parking light flasher relay . If the vehicle you are working on has +12 volt switched parking lights, connect this wire to a fused + 12 volt source. (Max. 15 Amps)

NOTE: If the vehicle's parking lights are ground switched, connect this wire to chassis ground. White Wire: Parking Light Flasher Output

This wire is the normally open contact of the on board parking light flasher relay . Connect this wire to the vehicle parking light feed wire. See diagram below for details on wiring positive switched parking light circuits.

Purple Wire: (+) Door Trigger Input

If the vehicle's door courtesy light switches + 12 volts when the door is opened, (Most Fords and some Imports), you must connect this wire to the positive output from one of the vehicle's door pin switches. In most cases, the Purple wire will need to be connected to only one door switch no matter how many doors the vehicle has as most door lighting circuits are wired in parallel. See below for wiring details.

Positive Door Switch Wiring Detail

Dark Green Wire: (-) Instant Trigger Input

This is the instant on ground trigger input wire. This wire must be connected to the hood and trunk pin switches previously installed. Note: This wire will be shunted when remote control channel 2 is accessed, (trunk release). This wire

will remain shunted all the while there is ground present and for 5 seconds after the ground is removed. This allows the operator to open the trunk via the remote transmitter without having to first disarm the alarm system. See below for wiring detail.

Hood Pin Switch Detail

Light Blue Wire: Ignition 3 Output

This wire provides a 300mA ground output that becomes active 3 seconds before the Remote Start Unit initializes, and remains grounded while running plus an additional 4 seconds after the Remote Start Unit turns off. In all of the applications described below, a relay will be required. The Light Blue 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 Remote Start activation period, then vibration from the running vehicle can cause the alarm to trigger. In this case, connect the Light Blue 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:

Some newer vehicles use a third ignition wire which is required to start and keep the vehicle's engine running. If this is the case, connect the Light Blue 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:

If the vehicle has the General Motors V A TS system installed, you will need to by-pass the system while the vehicle is operating under the control of the Remote Start Unit. To Do This;

1. Measure the resistance of the resistor pellet on the ignition key then select a resistor within 5% of the key's value from the resistor pack supplied.

2. Locate the pair of VATS wires in the vehicle, usually a pair of thin gauge wires running from the ignition switch to the VATS control module.

NOTE: These wires are typically White w/ Black trace and Violet w/ Yellow trace, however in later model

Cadillacs, they are run through an orange sleeve, and are either both Black, both Yellow, or both White wires. Consult the factory service manual for additional information.

3. Connect the Light Blue Wire from the Remote Start Unit to terminal #86 of an ex ter nal re lay. Connect terminal #85 of the relay to a fused + 12 volt battery source.

4. Cut (#1) wire (as shown), and connect the ignition switch side of the cut wire to terminal #87a of the relay. Connect the other side of the (#1) wire to terminal #30.

5. Connect the previously selected resistor from terminal #87 to the second (#2) wire (as shown).

NOTE: The above information and following diagram is for the GM VATS system only. For GM PASS

LOCK System you will require the Audiovox AS-PASS II Module. Green w/ White trace Wire: Entry Illumination Ground Output This wire provides a 30 second ground output (300 mA Max.) whenever the remote is used to disarm the alarm or to unlock the doors and provides a continuous pulsed output whenever the alarm is triggered. This wire should be connected to an external relay, and wired to the vehicles interior entry lighting whenever the optional Interior Illumination circuit is desired. See below for relay wiring details. Grey w/ Black Trace Wire: Negative Inhibit Input The Grey w/ Black Trace wire provides an instant shutdown for the Remote Start Control Module whenever it is grounded. Connect the Grey w/ Black trace wire to the hood pin switch previously installed. This wire must be routed through a grommet in the firewall and connected to the hood pin switch. If the pin
