2. Route the power input cable from the cradle’s power port to the connection point for the vehicle’s power
source.
3. When using the supplied in-line fuse holder (which must be used if not connecting to vehicle’s fuse panel):
a. Ensure the fuse holder contains a 5A UL Listed slow-blow fuse.
b. Splice the fuse holder to the end of the red V+ wire, as shown above. Make the distance from the fuse
to the power connection point as short as possible.

4. Prepare the cable termination.
a. Red wire: connect to a +12/24 V vehicle power source.
b. Black wire and Shield wire: connect to vehicle ground wire or chassis ground.
5. Connect the power input cable into the power port on the cradle.
CAUTION The means of routing and securing the power input cable from the cradle through to the vehicle power
source is extremely important. Hazards associated with improper wiring can be severe. To avoid
unintentional contact between the wire and any sharp edges, provide the cable with proper bushings
and clamping where it passes through openings. If the wire is subjected to sharp surfaces and excess
engine vibration, the wiring harness insulation can wear away, causing a short between the bare wire
and chassis. This can start a fire.
To avoid any mishaps, all wiring should be routed away from moving parts, high temperature areas and
any contaminants.

NOTE How the cable terminates depends on the vehicle. If the vehicle has a power output connector, then you
must attach a mating connector to the end of the power cable. You may be able to connect to a fuse panel
with a simple blade terminal or commercially available connector. Consult the vehicle Owner’s Manual for
information on how to access the power supply in the vehicle.
