The AA-925 Keyless Entry System is designed to provide a convenient electronic means to gain access to the vehicle by
providing RF remote control over the vehicle's power door lock system. The unit also includes outputs to control the
vehicle's dome lights, as well as exterior parking lights. Although not an alarm system, this unit also incudes a starter
interrupt circuit output. It also includes two additional auxiliary outputs designed to allow for control over optional devices
such as a power trunk release or engine starting device.

BEFORE BEGINNING THE INSTALLATION:

1) Find locations to mount the following items:
Control Module
Dash Mounted LED
Valet/Program/Manual Override Switch

2) Determine the type of factory power door lock system in use. Knowing the type of system before beginning

the installation can make the installation easier and faster since you can build whatever interface (if needed)
beforehand.

3) Determine whether the vehicle includes a power trunk release system and if so what type it is.

INSTALLATION OF COMPONENTS:
CONTROL MODULE:

The Control Module is NOT waterproof, DO NOT mount it in the Engine Compartment. Select a mounting location under
the dashboard. Choose a mounting location that will not interfere with proper operation of the vehicle's steering column
mechanism and brake and gas pedals. Secure the Control Module in the chosen location. Wait until all components
have been installed and all connections made before plugging in the main connectors.

DASH MOUNTED LED:

The small Red LED included in the kit serves as a visual indicator of the system's status and provides a visual deterrent
to a potential thief. The LED also provides important feedback information during the transmitter and feature program
modes. The LED should be installed in the dashboard in a highly visible area that may be seen from the driver’s seat as
well as from outside the vehicle. Try to choose a location close enough to the Control Module so that the LED's wires will
reach. Carefully inspect the area behind your chosen location to insure that the drill will not penetrate any existing factory
wiring or fluid lines. Drill a 1/4" hole and pass the connector end of the LED through the hole and route the wires toward
the location of the Control Module. Press the LED firmly into place until it is fully seated.

VALET / MANUAL OVERRIDE SWITCH :

Since much of the use of this switch by the vehicle operator requires concurrent operation of the ignition key switch, it is
recommended that the Valet / Manual Override Switch be placed such that it can be reached by the driver's left hand, while
they operate the ignition key switch with their right hand. 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 opposite side. 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 wires and connector toward the location of the Control Module.

RED Wire (Connects to RED/WHITE wire at harness plug): Main 12 Volt Input Wire
These are the main power input wires for the system. Both wires connect to a separate fuse holder contained in the
harness. These fuse holders each hold a separate ATC fuse, one 5AMP and one 10AMP. This RED wire must be
connected to a constant power wire at the vehicle's ignition switch harness or fusebox.
Locate a constant power wire at the vehicle's ignition switch harness. This wire will read +12VDC at all times, regardless
of the position of the ignition key switch. Attach the RED wire of the harness to this point by splicing and taping the
connection.

YELLOW Wire: Ignition Input Wire
This wire provides the system with an ignition power input from the vehicle. Connect this wire to the Ignition wire (primary
ignition wire) from the ignition switch. This vehicle wire will show +12VDC when the ignition key is turned to the "ON" or
"RUN" position
"OFF" and "ACCESSORY" positions.
Locate an ignition power wire at the vehicle's ignition switch harness. By splicing and taping the connection, attach the
YELLOW wire of the system to this point.

WHITE Wire: Positive Parking Light Flash Wire
This wire is designed to output a +12VDC positive light flash output, driven by the UNITS's internal relay, to be connected
directly to the vehicle's positive parking light circuit. Once the wire is located, confirm that all the vehicle's parking lights
will illuminate when +12VDC is connected to it.

and when turned to the "START" or CRANK" positions and will have 0VDC when the key is turned to the

NOTE: Some vehicles, (mostly European) have isolated "left" and "right" side parking lights. To connect to the parking

light systems in these vehicles, you must use separate SPDT relays to connect to each side in order to keep them
isolated. Attach the WHITE wire of the system to this point.

BROWN Wire: Negative (-) Door Sense Input Wire
If the vehicle's interior lights are controlled by
vehicles), the Brown
cases the factory door pin switches are wired in parallel, making it necessary to connect to only one door switch in order
to detect the opening of all doors. In a few cases this will not be true, making it necessary to connect to the vehicle dome
light, which typically is the intersection point of all doors.
Locate the vehicle's negative door trigger wire in the vehicle's kick panel or underdash. Connect the BROWN wire of the
system to this point.

PURPLE Wire: Positive (+) Door Sense Input Wire
If the vehicle's interior lights are controlled by

positive door sense wire should connect to one of the vehicle's factory door pin switches. In many cases the factory

Purple
door pin switches are wired in parallel, making it necessary to connect to only one door switch in order to detect the
opening of all doors. In a few cases this will not be true, making it necessary to connect to the vehicle domelight, which
typically is the intersection point of all doors.
Locate the vehicle's positive door trigger wire in the vehicle's kick panel or underdash. Using the appropriate connector,
attach the PURPLE wire of the system to this point.

BLACK Wire: Main System Ground
This is one of the most important wires of the installation. It must be connected properly to a solid chassis ground.

Special care must be taken to locate a clean metal part of the chassis as an attachment point for this wire. Some
installers prefer to locate a sturdy metal bolt under the dashboard or at the kick panel and use it as the attachment point.

If you find a suitable factory bolt that reads ground when tested, attach a ring terminal connector to the Black wire, remove
the bolt, place the ring terminal over the bolt and reinstall it, tightening it securely. If you choose instead to drill your own
mounting hole into the vehicle's chassis, be certain to remove any paint or grease and secure the ring terminal.

BLACK/WHITE Wire: Horn/Siren Output Wire
This wire provides a ground output (300 mA Max.) designed to drive a relay, which in turn can drive either the vehicle's horn

or an optional electronic siren. Depending upon which sounding device you decide to drive, the Black/White output wire
must first be programmed to control either the Horn or the Siren. The factory default setting is for the wire to control the
horn. Please refer to the section titled; "Programming System Features" later on in this manual for the programming
procedure.

To connect this output to drive a vehicle horn, locate the vehicle's horn wire, almost always a negative switched wire,
(typically found among the wires of the steering column), and connect it.

BLACK/WHITE Wire: Horn/Siren Output Wire
This wire provides a ground output (300 mA). To connect this output to drive an optional siren, a relay must be used to

convert the negative output to a positive output. The output wire must be programmed for siren output. Please refer to the
section titled; "Programming System Features" later on in this manual for the programming procedure.

Find a suitable mounting location for the siren and mount it properly. Run the siren's positive wire into the passenger
compartment to the location of the system and connect it to the additional relay.

GREEN/WHITE: Dome Light Supervision Output Wire
This wire provides a 30 second ground output (300 mA Max.) whenever the remote is used to unlock the doors. This
allows for the illumination of the vehicle's interior before entry. It also provides a flashing output that duplicates the p arking
light output flash rate whenever the "Panic Mode" is engaged. This wire must be connected to an external relay and wired
to the vehicle's interior entry lighting whenever the optional Interior Illumination feature circuit is desired.

DARK BLUE Wire: Delayed 300mA Pulsed, Channel 2 Output
The Dark Blue wire supplies a 300mA ground pulsed output whenever channel three of the receiver is accessed.
Pressing Button 3 for three seconds will access Channel 2. This is a low current output and must be connected to a relay
to supply power to the trunk release or the circuit you wish to control. Connect the Dark Blue wire to terminal # 86 of a
VF45F11 P&B relay or equivalent. Connect terminal # 85 of the relay to a fused +12VDC source. Connect the common,
normally open, and normally closed contacts of the relay to perform the selected function of Channel 2.

negative door sense wire should connect to one of the vehicle's factory door pin switches. In many

grounding door pin switches (typical of most GM, Chrysler, and import

+12VDC (Positive) door pin switches (typical of most Ford vehicles), the
