Installing the Handsfree Kit
1
Connect the 
GREEN
 Ignition Sense wire to an 
ignition-switched location on the fuse block. When the 
ignition is off, the ignition sense line is low. 
2
Connect the 
YELLOW
 Entertainment Mute Wire to the 
vehicle’s entertainment system. 
Note: 
This feature is only operational if the vehicle’s 
radio supports this capability. Installation may require 
an optional relay (not included). The mute line is an 
active low signal.
3
Connect the 
RED
 positive battery lead to a point in the 
vehicle’s fuse box that is fused at 5 amp. 
4
Connect the 
BLACK
 ground wire to the vehicle chassis. 
5
Inspect all connections.
Note: 
The 
ORANGE
 and 
BLUE
 wires are not used. 
(These wires are used to connect the line-level audio to 
the vehicle radio, if the radio supports this feature.)
Note: 
The system's handsfree audio has been optimized 
for the external speaker. Routing the audio output through 
the vehicle's entertainment system may alter the 
handsfree audio performance.
