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
grounding door pinswitches (typical of most GM, Chrysler, and
import vehicles), the Brown
negative door trigger wire should connect to one of the vehicle's factory door pin
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
+12VDC (Positive) door pinswitches (typical of most Ford vehicles),
the Purple
positive door trigger wire should connect to one of the vehicle's factory door pin 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 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.
