Installations using Adapter Cable Digital Inputs
If you are using the adapter cable digital inputs in your installation, the
following additional tools and other items may also be required:
• Crimping Tool
• Multimeter
• Fuse Tap - Required to obtain +12 V from the fuse panel.
Planning the Installation
Installation of theDriveRight OBD is simple. Unless you are using the
two digital inputs on the adapter cable, you only need to plug the OBD
cable into your vehicle’s OBDII port and then install the DriveRight
console.
The digital inputs on the DriveRight 600
E adapter cable may be used to
monitor any 12 VDC electrical device or accessory in the vehicle, but
they are typically used for monitoring accessories like the brake lights,
headlights, or seat belts.
To install DriveRight OBD:
1. Plug the OBD cable into your vehicle’s OBDII port.
2. Connect the digital inputs (if used).
3. Install the DriveRight console in the vehicle.
4. Test the DriveRight installation.

Procedure 1: Connect OBD Cable to OBDII Port.
1. Locate the OBDII port in the vehicle.
The OBDII port will be located within 3 feet of the steering wheel,
usually within the general area indicated by the dotted line in the
illustration below. The port should be easily accessible by a person
sitting in the driver’s seat without the use of tools.

Look in the follow areas if you have trouble finding the OBDII port:
• Under the dash
• In front of the passenger seat
• Behind the ash tray
• Behind a small access panel in the dash
• In or around the center console
2. Plug the OBD cable into the port.
Indicator Light

Note: The indicator light blinks three times when first plugged in, then blinks twice per
second until the connector establishes communications with the OBDII computer.
When communication has been established, the indicator blinks once then
remains off.
Note: The ignition must be ON to establish communication.
Note: When the vehicle is driven, the indicator blinks once for each speed reading.
Procedure 2: Connect the Digital Inputs (if used)
T wo 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. An example of a digital input configuration may
be Digital Input 1 connected to the brake lights while Digital Input 2
connected to the headlights. In the DriveRight Fleet Management Software (FMS), 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 module.
• The adapter cable is required for DriveRight 600
E even if you do not
use the digital inputs.
Note: 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.

1. If you are installing a DriveRight 600E OBD but not using the digital
r
inputs, go to Step 10 of this procedure.
2. Butt splice the red fuse holder to the red wire from the adapter cable.
3. Tap the red fuse holder to an unswitched +12 V source using the inline splice provided with your DriveRight or using a fuse tap connector (not included) appropriate for your vehicle.

Red +12V Wire with Fuseholde
You can obtain +12V from several places. Usually, you can easily
obtain +12V from the fuse box using a fuse tap connector (not supplied) or using the supplied in-line splice connectors to tap into a
known circuit that does not involve safety related equipment such as
headlights, tail lights, air bag, etc. Possible candidate wires include
those from the cigarette lighter, dome light, glove compartment
light, clock, tail gate light, or other convenience functions.
If you are getting +12V from your fuse box, use a fuse tap connector
appropriate for your vehicle.
4. Butt splice the black ground wire from the adapter cable to black
ground wire included with your DriveRight.
5. Crimp a spade
terminal,
included with the
unit, to the other
end of the black
wire. Refer to the
illustration.

7. Use the in-line butt splices to connect the blue wires with fuses to the
Green (Digital Input 1) and Yellow (Digital Input 2) wires from the
adapter cable.
8. Connect Digital Input 1 to the desired circuit.
9. Connect Digital Input 2 to the desired circuit.
10.Connect the digital input cable to the OBD cable.
It is easiest to make the connection by first holding the OBD cable
connector by the housing. Then hold the adapter connector on the
cable itself next to the sliding connector housing and push the two
connectors together. The two cables will lock together when properly connected.
Note: To disconnect the cables, hold the both cables by the housing and pull apart. The
sliding housing on the adapter cable connector will release the lock and allow the
cables to be separated.

Procedure 3: Install the DriveRight Console
1. The DriveRight console can be mounted in a number of places,
including the top of the dash, on the face of the dash, or on a sun
visor. Some of the different mounting choices are illustrated below
and on the following page:

3. Connect the DriveRight console cable to the adapter cable.

Console CableOBD or Adapter Cable
Hold cables as shown to connect. The connector housing on the console
cable slides back when you make the connection, allowing the cables to lock together.
Note: T o disconnect the cables, hold the both cables by the connector housing and pull
apart. The sliding housing on the console cable connector will release the lock
and allow the cables to be separated.
Once plugged in, the console should “wake-up” into the Current
Readings screen. If the display remains blank, make sure the battery
is properly installed in the unit. If it is, try pressing MODE. If the
screen remains blank after pressing MODE, press both MODE and
PLUS simultaneously. If it remains blank after that, check the
OBDII port connection.
Procedure 4: Test the Installation
1. T ake a test drive and verify that the console displays vehicle speed.
2. If the speed shown in the DriveRight console appears to be off,
check the console’s calibration. You can calibrate DriveRight in the
vehicle using the instructions in your DriveRight User ’s Guide, but
you will have much better accuracy with the DriveRight OBD if you
calibrate it in the DriveRight software using the following settings:
• PPM (pulses per mile) = 75,000
• PPR (pulses per reading) = calculated by software
• Calibration Number = calculated by software
Note: If you are using DriveRight FMS 3.1 or later, just select the “OBD” installation
method in the Device Settings dialog box when you configure the DriveRight
console.
