Step 2 - Red +12 Volt Wire
Connect the RED wire with its in-line fuse holder and 15 amp fuse to
the +12 volt ("+") side of the battery terminal, using our eyelet
connecter. To do so, simply unscrew the battery terminal connector
nut and then slip the eyelet over the bolt and retighten the nut.
Step 3 - Blue Current Sense Disable
Wire
This optional wire will shut off the current sensing feature of this
alarm. This needs to be done if the vehicle's fan motor stays on after
the engine has been shut off on a hot day. Addtionally, some newer
vehicles will have electronic modules that come on and off periodi-
cally after the engine has shut down. If the siren periodically acti-
vates for no explanation after your car was recently parked, then you
may need to connect this wire to shut off the current sense feature.
To disable the current sense feature, connect the Blue wire to a con-
stant +12 volt source. To enable ignition sense, see Step 5.
Step 4-Yellow Lights Wire
This wire can power up either the headlights or the parking lights of
your vehicle. You cannot connect both. Connect the Yellow wire to the
light wire that shows +12 volts whenever the lights are turned on. This
output is a +12 volt relay output. This output will flash the lights for
panic alarm & car finder features, plus let you turn on your lights to light
your way at night.
We recommend that you connect the YELLOW wire to
the parking light wire that measures +12 volts when the
parking lights are on. This will give a visual indication
from both the front and the rear of the vehicle.

This wire will is only needed if you have connected the Blue current
sense disable wire in Step 3. This wire will sense the ignition of the
vehilce being turned on and therefore sound the alarm should the
ignition be turned on while the alarm is armed. Connect this wire to
a wire that measures +12 volts whenever the ignition is turned on.
