Black Widow BW 4150 Installation Manual page 2

Main Harness:
• BROWN WIRE - Siren wire output (+) 3A.
Connect to the siren's red wire. Connect the
siren's black wire to ground.
• BLACK WIRE - Ground input (-). Connect to
a solid chassis ground that is clean and free of
paint or dirt.
• ORANGE WIRE - Armed Output (-) 500mA.
Connect to a relay for optional circuit defeat
(See installation diagrams). The ORANGE wire
provides a ground when the unit is armed to
activate a fuel pump disable relay or other
device (i.e. window control module, etc.).
• BLUE/BLACK WIRE - Optional sensor input
(-). Connect this wire to the trigger output of
an optional sensor.
• YELLOW WIRE - +12V Ignition input.
Connect to a main ignition wire at the ignition
switch harness.This wire shows +12V when the
ignition is on and while cranking. The voltage
must not drop when the car is starting.
• BROWN/WHITE WIRE - Horn output (-)
500mA. Connect to an optional relay to activate
the vehicle's horn when the alarm is triggered.
• BLACK/YELLOW WIRE - Auxiliary 3 output
(-) 500mA. Connect to a relay for an optional
feature such as headlight activation, etc. This
output may be programmed for momentary,
timed, or latched operation.
• GRAY WIRE - Auxiliary 1 output (-) 500mA.
Connect to a relay for optional features such as
trunk release, etc. This output is programmable
for momentary, timed, or latched operation.
• WHITE WIRE - Parking Light output (+/-)
10A relay. Connect to the vehicle's parking light
wire. If the vehicle's parking light circuit exceeds
10 amps a relay is required. For vehicle's with
independent left and right parking light circuits,
the parking light wires must be connected using
diodes to keep the circuits separate. NOTE: Do
not connect the WHITE wire to the vehicle's
headlight circuit.
• RED WIRE - +12V Battery input.
the red fused wire on the main harness to a
constant +12V source.This source wire should
be at least 20 amp supply.
• BLACK/WHITE WIRE - Dome Light output
(+/–) 15A relay. Connect to the wire that
activates the vehicle's dome light, usually the
door pin switch wire. NOTE: The dome light
output is usually connected to the same wire
used for the door trigger input (See GREEN
and VIOLET door trigger wires).
• BLUE/WHITE WIRE - Passenger Unlock
output (-) 500mA. Connect to an optional relay
to unlock the passenger doors when the system
is configured for Driver Priority Unlocking.
• WHITE/RED WIRE - Auxiliary 2 output (-)
500mA. Connect to a relay or module for an
optional feature such as power window
activation or remote start, etc.This output may
be programmed for momentary, timed, or
latched operation.
• VIOLET WIRE - Positive door trigger (+).
Connect to the door switch circuit wire that
shows +12V when the door is open. This type
of door circuit is usually found on Ford vehicles.
• GREEN WIRE - Negative door trigger (-).
Connect to the door switch circuit wire that
shows ground when the door is open.
• BLUE WIRE - Trunk/Hood trigger (-). Connect
the Blue wire to the trunk and/or optional hood
pin switches.The switch must provide a ground
output when switch is opened. If the optional
remote start module is installed, connect the
blue wire to the trunk pin switch only and
connect the hood pin input on the remote start
module to the hood pin switch only.
