Additional DriveRight Documentation Refer to the following documents for information on configuring and using your DriveRight: • The DriveRight User’s Guide included with your unit. • The on-line help in the DriveRight software. • The DriveRight FMS User’s Manual located in an Adobe Acrobat PDF file in your DriveRight program directory. Tools and Materials Needed DriveRight installation may require some or all of the following tools and materials. Please review the installation instructions and make sure you have all necessary items before proceeding with the installation. All Installations

• Electric Drill with 7/64” (2.5 mm) Drill Bit - Used to drill tap holes for #6 self-tapping screws. • Medium Phillips Screwdriver • Pliers


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 The installation for DriveRight OBD is very 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 adapter cable may be used to monitor any 12 VDC electrical device or accessory in the vehicle, but they are typically used to monitor 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; DriveRight 600 only). 3. Install the DriveRight console in the vehicle. 4. Test the DriveRight installation.


Wiring Diagram The diagram below provides an overall picture of DriveRight OBD wiring.

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 OBDII Port

OBD Cable

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 being driven, the indicator blinks once for each speed reading.

Procedure 2: Connect the Digital Inputs (if used) 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 is connected to the brake lights and Digital Input 2 is connected to 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 module. • The adapter cable is required for DriveRight 600 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 600 OBD but not using the digital 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. In-Line Splice

Unswitched +12V from Vehicle

Trim off flush stripped wire

Red +12V Wire with Fuseholder

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 Vehicle unit, to the other Ground end of the black Crimp Tool, 22-18 AWG Position Spade wire. Refer to the (red dot) Terminal illustration. 6. Connect the Black Ground Wire 3/16 - 1/4" spade terminal to (22 AWG) (5 - 6 mm) a vehicle chassis ground.


Note: Test the vehicle chassis ground using a multimeter before connecting the ground wire.

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, typically the brake light circuit. 9. Connect Digital Input 2 to the desired circuit, typically the headlight 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: Face of Dashboard Mounting Options Double-Sided Foam Tape

2. Insert the battery into the DriveRight console.

3. If you are installing a DriveRight 600, connect the DriveRight console cable to the adapter cable. If you are installing an earlier model of DriveRight, connect the console cable directly to the OBD cable. It is easiest to make the connection by first holding the OBD cable connector or adapter cable connector by the housing. Then hold the console cable 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 connector housing and pull apart. The sliding housing on the console cable connector will release the lock and allow the cables to be separated.

Console 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.

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 the MODE and PLUS simultaneously. If it remains blank after that, check the OBDII port connection. Procedure 4: Test the Installation 1. Take a test drive and verify that the console displays the 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.
