Connecting the
Power Cable
Important
Although it is possible to connect the radio in line with the
vehicle ignition, this is not recommended, as it may draw
too much current and damage the vehicle wiring and
steering column or ignition switch. This may also cause the
supply voltage of the radio to drop below the specified level.
Important
Disconnecting the vehicle’s battery may cause problems
with some electronic equipment, such as vehicle alarms,
engine management systems, and in-car entertainment
systems. Check that the vehicle owner has the necessary
information to make all electronic equipment function
correctly after battery reconnection.
Important
If the battery is not disconnected, exercise extreme caution
during the installation and install the fuses only when the
installation is ready to be checked. For more information,
refer to
“Checking the Installation” on page 27
.
1.
Disconnect the vehicle’s battery unless specifically prohibited from
doing so by the customer, vehicle manufacturer, agent, or supplier.
Important
Route the cable in a manner that minimizes coupling of
electric vehicle systems such as alternators into the radio.
Important
Protect the power cable from engine heat, sharp edges and
from being pinched or crushed.
2.
Run the power cable between the radio’s mounting position and the
power source and cut it to length, allowing approximately 8 inches
(20 cm) excess at the radio end.
3.
Plug the power cable into the power connector of the radio.
4.
Cut the negative and the positive wires where the in-line fuse holders
will be placed (as close to the power source as possible).
Important
Do not install the fuses until the installation is ready to be
checked. For more information, refer to
“Checking the
Installation” on page 27
.
5.
Insert each end of the negative wire into each of the fuse
crimp-terminals and crimp them to force the metal contacts onto
the wires.
6.
Push the two crimp-terminals into the clear plastic fuse cover. Close
the cover while the next steps are completed.
7.
Repeat steps 5 and 6 for the positive wire.
8.
Connect the negative wire to the battery ground terminal
9.
Connect the positive wire to the battery positive terminal.
