The cable shipped with your device includes an in-line fuse holder and a 2-amp fuse. The
fuse should be removed from the fuse holder before the install process and
should not be replaced until everything else has been installed, the cable is
connected to the device, and you are ready to use the device. Installing the fuse
should be your last step to complete the installation.
2.6
Red - Constant Power (Required)
Locate a suitable 12 or 24 volt constant power source. Acceptable sources for power are:
The fuse block, ignition harness or vehicle’s battery.
• Fuse Block: If you choose to get power from the fuse block on your vehicle, you can
use a fuse tap and a female quick disconnect. The fuse tap must be installed on the
hot side of the fuse. To find the hot side of the fuse, remove the existing fuse from the
fuse block and use a test meter to probe the fuse socket. The side that shows 12 or 24
volts DC is the hot side of the fuse where you should insert the fuse tap.
• Ignition Harness/Vehicle’s Battery: If you choose to get power directly from the
battery or another wire on the vehicle be sure to use a suitable connector or splice
method (such as soldering) to ensure a permanent connection. The device will not work
without power.
2.7
Black - Ground (Required)
Locate a suitable area for grounding the device that is free from paint, dirt and grease.
Securely fasten the black wire from the cable to the ground source using a suitable crimp
terminal.
2.8
Yellow - Key On and Crank (Recommended)
This installation is recommended for more accurate trip information. Locate a “key on
and crank” power source using a test meter. Connect the yellow wire from the cable to
this power source. This wire should test hot is both on and start positions.
Note: Most vehicles include a number of sources for Constant Power, Ground,
and Key On power under the dash. It is up to the installing technician to choose
the best sources for the particular vehicle.
2.9
GPS Antenna Installation
Depending on the type of antenna provided, locate a suitable place on your vehicle to
install the antenna.
For optimal performance, the GPS antenna should be mounted under the top of the dash
pad without being obstructed by any metal. While you can mount the antennas elsewhere,
performance may suffer as a result. Please ensure that the non-magnetic side has
unobstructed view of the sky. Any metal construction will restrict or diminish GPS
reception.
Make sure there is sufficient cabling to reach from the point of the antenna mount back to
the point where you have installed the SkyGuard device. Conceal any excess cable under
the carpet, trim, or dash so it will not be exposed to wear. Be careful not to crimp or kink
the cable as this may damage the antenna or reduce its effectiveness.
