Parking Light Wiring
The park like wire
is simply a wire that when the security system has alarmed, disarmed
or an alarm state Will flash the parking lights depending upon the
status at a specific rate.
|
|
|
For example, most systems when all
armed will flash park lights wants, win disarmed will flash twice
and flash constantly went in the alarm state.
You may be wondering
why you would need to have the park lights flash for any security
system, however it's purpose is mostly for situations where you may
not be able to hear the chirp confirmation that most security
systems incorporate,
|
in
situations such as being in a building or home where the
chart confirmation is not audible from
your position, on most security systems park like wire will
typically be one wire that sends a negative pulse two the
vehicles parked light wire.
Most vehicles
require a negative
voltatge to activate park lights, however many security
systems may have a program switch to transfer the polarity from
negative to positive for vehicles requiring a positive
signal for park lite activation.
The most common place to find the wire
that goes to the factory parking lights is right below the steering
column, at light swithc or at BCM (Body Control Mouduial)
Ther are several wiring
configurats that are used to actavat vehicle parking lights:
-
Negativ signal
-
Posative signal
-
Dule circuit
-
Data bus

What do I have?
How to determine what
type of relay configuration your vehicle has.
You can verify
the type of system used by using a digital test light (for
safety to the cars electronics) or a voltage meter.
You should begin
by locating the wire that sends the specific voltage and
while turning the vehicles light switch to the PARK LIGHT ON
POSITION ONLY. Be sure to only actavvat the parking lights
and not the headlights, as this will give a false signal to
the test ligh.Most vehicles headlight switch will actavat
all iluminatins systems on the entire vehicl.
Many
vehicles will incrperat several differant differat circuist
on ther iluination cuicuit:
-
In most cases you
can find the harness to the power sunroof at the driver or
passengers kick
panel, witch is basically the panel that your left foot (if
drivers)
"hangs" around when driving.
-
Most vehicle kick panels will
snap off or will have a screw or two holding it in place.
Remove the kick panel to reveal the harness that goes from
the vehicle through the door jamb and into the door.
-
Usually
you will find the culprit at this harness.

About this circuit:
-
This type circuit is used when the
vehicles park light trigger wire requires a (-)
negative voltage to activate the park light feature.
-
The remote
entry or security system sends a negative pulse to the
park light circuit or
B.C.M. (body control module) where it then activates the
park lights.
-
Connect the
park light wire from the remote entry or security
system directly to the park light wire located in the
vehicles wiring. For vehicle specific
wiring information see
Car Stereo and Security Wiring Diagrams
park light wire
location, polarity and wire color.
-
Most remote
entry and security systems will have the option to send
a negative or positive voltage out. Be sure to change
this setting on the remote entry before wiring
-
If your
remote entry does not have the selectable positive or
negative it will most likely be a negative. use the
circuit below to convert the negative voltage to a
positive voltage. See Positive pulse with
relay.

About this circuit:
-
This is the
same as above but this type circuit is used when the
vehicles park light trigger wire requires a (+)
positive voltage to activate the trunk pop feature
-
The remote
entry or security system sends a positive pulse to the
park light circuit or
B.C.M. (body control module) where it then activates the
park light motor or solenoid.
-
Connect the
park light wire from the remote entry or security
system directly to the park light wire.
-
If you do
not have a volt ohm meter to measure the resistant values see
Car Stereo and Security Wiring Diagrams
for vehicle specific door lock resistor values, wire
location and wire color.
