existing bolt in the vehicle and securely ground the wire.
BLUE and RED Starer Interrupt wires (from relay socket; optional):
These wires are used the interrupt the vehicle’s starter circuit in a vehicle
theft scenario. Locate the vehicle’s starter wire (typically found in the ignition
switch harness). It will show +12V when the ignition key is turned to the START
position. Cut the starter wire and connect the BLUE and RED wires to each side
of the cut wire. These are not polarized so it does not matter which side is used.
YELLOW Unlock output wire (PIN 11; optional):
This is a negative pulse output typically used to unlock the vehicle’s
doors. It has a 0.25 second, 250mA output. Depending on the vehicle, a relay
or doorlock interface may be required. Be sure to study the vehicle’s doorlock
system before making this connection. This connection is determined by the
vehicle’s design.
VIOLET Alarm trigger input (PIN 3; optional):
This is an input to detect when the vehicle’s alarm (factory or aftermar
-
ket) is triggered. This generates the notification to the end user to alert them of
the violation. This input must see pulses and can detect a positive or negative
input. It must see 10 pulses (20 polarity changes) within 30 seconds to activate
the notification. Connect this wire to the pulsing horn output of the alarm. If a
horn output is not available (typically with aftermarket alarms), you can connect it
to the flashing lights circuit.
BROWN Ignition wire (PIN 8; 18ga; fused; required):
This wire monitors when the ignition is turned ON/OFF. Connect this wire
to a +12V ignition circuit which can be found in the ignition switch harness. Be
sure this shows +12V when the key is in the ON and START positions ONLY.
RED Constant power wire (PIN 14; fused; in sheath; required):
This is the power supply wire to the device. It must be connected to a
co12V source. This can be found in the ignition switch harness, a fuse
-
block, or at the vehicle’s battery. Be certain that this wire has +12V under all
circumstances and when the ignition key is in the ON and OFF positions.
BEFORE CONNECTING, remove the 3 amp fuse from the RED wire.
ALL REMAINING WIRES ARE NOT USED FOR THIS DEVICE
Step 4: Move the vehicle outside
You must move the vehicle outside and make sure the device has a
“clear view of the sky” before applying power. This will ensure the quickest initial
GPS lock and the best cellular coverage.
