1 Disconnect the vehicle's battery.
2 Remove all fuses from the power adapter cable
and tape them to their respective holders.
DO NOT re-insert fuses until you complete
and inspect all connections.
3 If trimming the wire lengths on the power adapter
cable, be sure to leave the inline fuses on the
cable along with enough wire length to allow
connections to be made.
4 Connect the power adapter cable's GREEN
Ignition Sense wire (3 Amp fuse) to an
ignition-switched location on the fuse block.
When the ignition is off, the ignition sense line
should be low.
7 Connect the power adapter cable's BLACK
ground wire to the vehicle chassis.
Note: Skip steps 8 and 9 if your vehicle
entertainment system does not support the
telephone audio input feature, or if you are using
the external speaker (supplied). This feature is
only operational if the vehicle's entertainment
system supports this capability.
8 Connect the power adapter cable's ORANGE
wire to the (+) line-level telephone audio input
of the vehicle's entertainment system.
9 Connect the power adapter cable's BLUE wire to
the (-) line-level telephone audio input of the
vehicle's entertainment system.

5 Connect the power adapter cable's YELLOW
Entertainment Mute Wire to the vehicle's
entertainment system's mute input.
Note: This feature is only usable if the vehicle's
entertainment system supports an active low,
single wire, radio mute signal. Otherwise, the
installation may require an optional relay adaptor
(not included) or other customization.
6 Connect the power adaptor cable's RED positive
primary lead (4 amp fuse) to a point in the
vehicle's fuse box that is fused at 4 to 5 amps.
The RED positive primary lead should be powered
continuously. On/Off switching is performed by
the GREEN Ignition Sense wire.
Important: Do not connect the RED and GREEN
wires together. Doing so limits the functionality of
the car kit.

is on the overhead console/dome light
assembly near the front center of the vehicle,

16 inches (40 cm) from the driver.
