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
