Guidelines for Routing Cables
Many vehicles are equipped with wiring troughs in the doorsills. If your vehicle
includes this feature, use it to simplify cable installation and to provide
maximum protection for the cables.
In vehicles without wiring troughs, route cables according to these guidelines:
Route cables so they are protected from pinching, sharp edges, and crushing.
•
Where possible, avoid routing cables above the catalytic converter.
•
Use grommets wherever a cable must pass through a hole in a metal
panel.
•
In a vehicle equipped with electronically controlled anti-skid brakes, route
all cables on the opposite side of the vehicle from the braking modulator
box to minimize possible interference from the phone.
•
Keep all in-line connectors accessible.
The suggested path for routing cables in vehicles without wiring troughs is
alongside the drive shaft hump, under the carpet.
Wiring for Additional Features
Convenient On/Off Feature
The power cable includes a Green wire which, when connected to sense the
status of the vehicle ignition, enables the user of the mobile to conveniently
turn the phone on and off with the vehicle ignition.
Entertainment Mute Feature (optional)
The entertainment mute output connects to the mute input on your car radio, if
the radio includes a mute function. The entertainment mute feature
automatically mutes the radio when you place or receive a call. This feature
needs to be integrated with a car radio that supports this functionality.
Note:
This output signal from the “Mute” connector sinks a maximum of
100mA (0.1A) to ground.
Horn Alert (Ring) Feature (optional)
The horn Alert (Ring) output connects to the horn of the vehicle or other
device for alerting when an incoming call is received on the terminal.
Local laws and regulations regarding the connection of Audible horn Alerts
must be abided by. Please consult local authorities in your area prior to wiring
in this feature.
Note:
This output signal from the “Ring” connector sinks a maximum of
100mA (0.1A) to ground. Therefore it can only be used to drive a relay
(maximum coil current of 100mA), which in turn activates the horn.
DO NOT
connect this output directly to the horn.
