The PRO 9845 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, the PRO
9845 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 INSTALLA TION:

1) Control Module
Dash Mounted L.E.D.
V alet / Manual Override Switch

2) Determine the type of factory power door lock system in use. Knowing the type of system up front 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 NOTmount 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 L.E.D.:

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 feed back 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 recommened 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 PRO 9845 system. Both wires connect to a separate fuseholder
contained in the harness. These fuseholders 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 PRO 9845 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
0VDC when the key is turned to the "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 PRO 9845'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.

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 a 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 Trigger Input Wire

If the vehicle's interior lights are controlled by
import vehicles), the Brown
switches. In many cases the factory door pinswitches 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 negative door trigger wire in the vehicle's kickpanel or underdash. Connect the BROWN
wire of the system to this point.

PURPLE Wire: Positive (+) Door Trigger Input Wire
If the vehicle's interior lights are controlled by
the Purple
cases the factory door pinswitches 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 kickpanel 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 PRO 9845 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 kickpanel, 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 using the self taping screw and star washer provided.

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
To connect this output to drive an optional siren, 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 PRO 9845, and connect it.

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
with the PRO 9845. This allows for the illumination of the vehicle's interior before entry. It also provides a flashing
output that duplicates the parking 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 two of the receiver is accessed.
Pressing transmitter Button 2 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.
