Two digital inputs located on the adapter cable are available to monitor the on/off
state of lights, including brake lights, or of other 12 VDC electrical accessories.
Typically Digital Input 1 monitors the brake lights and Digital Input 2 monitors the
headlights. In the DriveRight software Digital Input 1 is recorded in the GPS table
and in the accident logs. Digital Input 2 is only recorded in the GPS table.
❏ You can record the digital input status during a trip by enabling GPS in
DriveRight FMS, even if you aren’t using the optional GPS module.
8hˆ‡v‚) Connecting the digital inputs can be hazardous to both the installer and your vehicle’s
electrical system if not done by an experienced installer. This manual assumes you are
aware of the inherent dangers of working in and around a vehicle and have a working
understanding of electricity.
If you are not using the digital inputs go to Step 6 of this procedure.
! Use an in-line splice to connect the
red +12 VDC wire from the adapter
cable to the red +12 VDC wire in the
harness cable. Be sure the tap is
protected by the harness cable fuse.
Refer to the “Wiring Diagram” on
page 4.
" Connect the black ground wire from
the adapter cable to chassis ground.
# Use in-line butt splices to connect the blue wires with fuses to the green and
yellow digital input cables.
$ Use the included T-Tap disconnects to connect Digital Inputs 1 and 2 to the
desired circuits.
% Connect the adapter cable to the harness cable.
To connect the harness and adapter cables, hold the harness cable connec-
tor by the connector housing and hold the adapter cable by the cable next to
the connector. Push the connectors together. The connector housing on the
adapter cable slides back when you make the connection, allowing the con-
nectors to lock together.
I‚‡r) To disconnect the cables, hold the both cables by the housing and pull apart. The sliding
housing on the adapter cable will release the lock and allow the cables to be separated.
