in the engine compartment, the easiest way to locate the parking light wire is to
access a corner running light on the fender, or a front parking light in the front
bumper or fascia. The correct wire will typically show +12 Volts when the
headlight switch is in the "Parking Light" and "Head Light" positions. It is also a
good idea to ensure that the target wire is "non-rheostated", or actually the dash
illumination circuit. While metering the wire, operate the dash light dimmer
control. The correct wire will show no change in voltage when the dimmer is
operated. Do not attempt to flash the parking lights by connecting the White wire
to a rheostated (dimmer) circuit! This will backfeed the parking lights through the
rheostat or illumination control module, and cause damage to the vehicle or the
system's control module and siren assembly. Rheostated light circuits are very
rarely found in the engine compartment, but testing the target wire anyway is
easy. A few vehicles have separate left and right side parking lights. When left
& right parking lights are on separate circuits, simply connect one White wire to
each parking light circuit. The White wires should be connected to the vehicle's
parking light circuit only- flashing the headlights is not recommended, as it is a
higher current draw, and halogen headlights are not designed to be rapidly
turned on and off.
Yellow Wire - (+12 Volts Ignition Input): Another wire which is not absolutely
necessary for basic system operation, the Yellow wire is an ignition "on" input to

Red Wire - (+12 Volts Input): This is the second of two wires in which connection
is required for the system to operate. The Red wire's function is to supply Constant
+12 Volts to the security system. As noted on the previous page, when +12 Volts
is first applied to the Red wire, the system will automatically enter Transmitter
Programming Mode. The Red wire also supplies +12 Volts to the built-in relay for
flashing the parking lights.
CONNECTION: Connect the Red wire to a source which has +12 Volts at all times.
Ensure that this source +12 Volts which is stable in all ignition key positions. There
are several possible connection points in the engine compartment, where the
250i6 is designed to be mounted. Connection may be made at an engine
compartment fuse/junction block (preferred) or at the battery itself. Most fuse/
junction blocks typically have power takeoffs, or open locations that can be
connected to with the proper terminal. Please note that connecting the Red wire
directly to the battery's Positive terminal will expose this connection to failure due
to a corrosive environment, so preventative steps should be taken, such as coating
the connection itself with White Lithium Grease or other protective compound.
The source used must have at least a 15 Amp capacity at all times.
Blue Wire - (- Ground Instant Trigger Input): The Blue wire, while not necessary
for the 250i6's basic operation, greatly increases the system's effectiveness. This
wire is a "- Ground instant trigger" used to detect entry into the hood
