Installing the Power Cable
1. Route the black lead of the main power cable to convenient chassis ground and
the red lead to the positive supply voltage connection points. If it is necessary to
penetrate the firewall, use an existing opening.
2. If necessary, drill a new hole approximately 9/16” or 3.5cm in diameter. Make
sure that there is enough clearance on the opposite side. Insert a grommet into the
hole to prevent damage to the power cable.
3. Cut the black lead to the desired length.
4. If the connection is being made under the dash or in the vehicle cabin, connect
the black lead directly to the chassis of the vehicle..
Note! Do not connect the black lead to the negative (-) battery terminal.
The car could be damaged if there were a malfunction in the vehicle’s electrical
system.
5. Cut the red lead to the desired length. This lead will be connected such that it has
positive supply voltage at all times, even when the vehicle is turned off.
6. If the connection is being made under the dash or in the vehicle cabin, connect
the red lead to a positive supply voltage point.
7. If the connection is being made in the engine compartment or directly to the
battery, connect the in-line fuse holder between the red lead of the power cable and
the desired positive voltage connection point.
8. Route and connect the green lead to a convenient ignition switch supply point in
the vehicle.

Stereo Mute
If the vehicle’s stereo system supports an external muting feature, route and
connects the orange wire to the car stereo system. Otherwise, the orange wire may
be left unconnected and cut off or tied out of the way.
NOTE! The Car Kit supports an “Entertainment Mute” function when connected to a
car stereo system that provides for external muting. This function is compatible with
systems that mute the audio output when the control line is connected to ground
Mounting the external vehicular Antenna
