Example of power connection to the fuse box
3.5.4 Connecting The Power Cable
Use the following procedure to connect the power cable (See Figure 3 on page 3-8 for a
diagram of the wiring):
Caution
The modem will not work if the vehicle doesn’t have a proper
ground. There are no fuses on the power cable because the
modem has an internal fuse.
1.
Connect
the Power (red) wire to a fused three-amp (3A) power lead. This is the
positive wire.
Warning
We recommend adding a three-amp (3A) safety fuse to the
power cable at the fuse box. This protects the modem and
prevents a potential fire hazard in the event of a short circuit
in the power cable.
2.
Connect
the Ground wire (black) to a
common vehicle ground. This is the negative
wire.
3.
Connect
the Ignition sense wire (green) to
the ignition switched terminal on the fuse
panel.
4.
Connect
the Alert (white) wire to the horn line
before the horn relay.
5.
Turn
on the ignition after you connect the
cables and check the voltages. Four LEDs
should turn on briefly. The SVC LED continues
to blink.
Note:
If you connect the power as shown in Figure 3 the alert only works when you turn
on the vehicle ignition.
