The Davis DriveRight™ is designed to allow straightforward installation. The specific details of installation vary by vehicle model and year. This manual provides
general instructions sufficient to guide a professional installer or knowledgeable,
experienced individual through a successful installation. Please read or at least skim
the
entire manual
before beginning the installation. Read and understand each step
thoroughly before starting that step. Your DriveRight includes a limited number of
extra parts. In this manual, parts will be referred to by their item numbers shown in
Figure 1.
WARNING:
P
The magnet supplied with the DriveRight is extremely strong and will de-magnetize
ATM cards, credit cards, etc., if brought in contact. It may also affect other sensitive
electronic equipment.

OURSELF INSTALLATION
Davis Instruments strongly recommends that the DriveRight be installed by ASE
(Automotive Service Excellence) certified technicians or professional automotive
mechanics. As with any installation of an automotive accessory, the installer must
make a series of decisions, in this case decisions such as where and how the sensor
and brackets are mounted, where holes are drilled, how wires are routed, where to
locate unswitched +12V and ground and so on. These decisions are best made by a
knowledgeable and experienced professional. Poor decisions may damage your vehicle or cause accidents or injuries.
If you select professional installation, use the procedure described in “Initial Test”
on page 18 to verify the work done.
WARNING:
G
Working beneath your vehicle and installing the DriveRight may be hazardous.
Improper installation may damage your vehicle and cause accidents and/or injuries. If
you are uneasy about installing your unit please have a qualified professional complete
the installation. Davis specifically disclaims any liability for injury or loss resulting
from the installation or use of the DriveRight.
ETTING READY
Before installing your DriveRight:
• You may need to raise the vehicle in order for you to work under it. Always use
safety stands when working on or under any vehicle that is supported by only a
jack.
• You may need the following tools or equivalent. Additional tools may be
required depending on your specific installation.
• drill and drill bits, 1/8” to 5/16” (3 to 8mm)
• multimeter and/or test light
• hacksaw
• adjustable wrenches
• vise
• metal forming tools
• crimp tools
• wire cutter

• wire stripper
• various screwdrivers
• pliers

NSTALLATION
Figure 2 illustrates the installation of the DriveRight. The sensor, sensor magnet
and associated brackets mount underneath your vehicle. Figure 12 on page 11 is a
sketch of a typical rear wheel drive sensor installation while Figure 17 on page 13 is
a sketch of a typical front wheel drive sensor installation. The sensor leads run
under the vehicle and into the vehicle cabin where they connect to the DriveRight
display. The DriveRight display also requires unswitched +12V and ground connections to your vehicle’s electrical system.
Before you begin the actual hands-on installation of your DriveRight, please plan
out your installation by thinking through the following points. This will save you
time, frustration, and parts.
• Determine how and where you want to mount the DriveRight display within the
vehicle cabin.
NOTE: Safe driving requires that the driver’s attention be focused on the road. Please install
your DriveRight in a location which minimizes distractions to the driver.
• Find a single point in the vehicle cabin where you can bring together the leads
of the harness cable, the sensor leads, and the +12V and ground wires.
• Determine how you will route the harness cable to the DriveRight display.
• Locate your fusebox and find a source of UNSWITCHED +12V NOT USED FOR
SAFETY RELATED EQUIPMENT.
NOTE: “Unswitched +12V” means +12V not switched off by the ignition key. The
DriveRight consumes negligible power (nominally, 5mA) and will not run down
your vehicle’s battery. The lithium 3.0V battery inside the DriveRight is not
rechargeable and is not charged by the vehicle’s battery.
• Locate a ground point to attach a ground wire spade terminal.
• Locate a feedthrough into the vehicle cabin through which you can bring the
two sensor leads and the +12V and ground wires if your fusebox is in your
engine compartment.
• IF YOU HAVE A FRONT WHEEL DRIVE VEHICLE, decide whether you will place the
sensor magnet on either the left or right side in-board constant velocity (CV)
joint hub.
• IF YOU HAVE A REAR WHEEL DRIVE VEHICLE, decide where on the driveshaft
within 12” (30cm) of the transmission you will place the sensor magnet.
• Decide how you will attach the brackets so that the sensor is within 3/8” - 5/8”
(10-16mm) of the magnet. How will you form the brackets to fit? What holes
will you use or drill to mount the bracket? Do these holes pierce the vehicle
floor? Where? (DO NOT USE FLUID RETAINING BOLTS AS MOUNTING POINTS.)
• Decide how you will route the wires from the sensor to a feedthru into the
vehicle cabin.
• THE WIRES SHOULD BE ROUTED AT LEAST 12” (30CM) AWAY FROM SPARKPLUG
WIRES, THE COIL, AND THE ALTERNATOR. AVOID LOOPS, COILS, AND FOLDS
SHOULD TO PREVENT UNWANTED INTERFERENCE THAT MIGHT RESULT IN
ERRONEOUS READINGS.

Step 1. D
ISPLAY
The DriveRight comes with the hardware necessary for a variety of display mounting options. The long harness cable (4) included with the DriveRight allows you to
install the display where you want it. You may, at your option, use the coiled cable
extension (3) for even greater convenience.
• Use the visor clip (5) to mount your display on a visor or door pocket. Install the
clip on the top or bottom of the display to orient the display as you wish (Figure
4). Push the clip in until the 3rd bump engages.
• Mount your display to the dash or center console. Choose a location and decide
how you want to mount the display: directly to the surface or using the mounting
bracket (6) and right angle adapter bracket (12). Then, decide how you want to
attach the display or the brackets: using VELCRO tape (15), double-sided foam
tape (14), or screws. Apply the two adhesive-backed loop tapes to the flats on the
back of the display (Figure 5) or to the back of the brackets. With the hook tapes
attached to the loop tapes, press adhesive backing of the hook tape onto your
selected mounting surface. Do not separate hook and loop tape for at least 24
hours after applying. Attach the mounting bracket to the right angle adaptor
bracket (12) with hardware provided as needed (Figure3). Mount the reversible
right angle adaptor bracket to desired location with hardware provided. Apply the
double-sided foam tape to mount the brackets if desired.
NOTE: For best results with foam tape or VELCRO, apply adhesive at room temperature of
68˚F (20˚C) or higher. Surface should be clean, dry and free of oils. Use clean wiping materials with a cleaner appropriate for your vehicle’s interior to free surface of
contaminates and allow to dry. Peel release liner from back of tape and apply. (Take
care not to touch the adhesive with your fingers.) If adhesive must be applied at temperatures lower than 68˚F (20˚C), warm substrate and the tape to elevate temperature prior to applying. This may help the bond cure. Allow 24 hours for full cure
before loading or cycling.

Step 2. +12V P
NOTE: Thinking ahead...In Step 5, you will bring the sensor leads, +12V wire, and ground wire to
a single point of your choice under the dash and connect them to the display harness cable.
Choose this single point now. The sensor leads must be led into the vehicle cabin. Usually
you can use an existing feedthru in the firewall. If your fusebox is in the engine compartment then you may also need a feedthru to bring the +12V and ground wires through into
the vehicle cabin.
The DriveRight requires an unswitched +12V connection to your vehicle and a
ground connection to the vehicle chassis. These connections are often most easily
made at your vehicle’s fusebox. A direct connection in your fusebox is best - some
vehicles have extra slots for accessories such as the DriveRight. You may need to buy
the proper termination for use with your vehicle’s fusebox - consult your dealer or
local auto parts store. Attach the termination or connector to the end of the red
+12V wire with fuseholder (16) and insert into your fusebox. Otherwise select an
unswitched
ment such as headlights, brakes and so on
the wires used for the cigarette lighter, dome light (before the switch), glove compartment light, clock, tail gate light and other convenience functions. The wire
used should be 22-18AWG or have the same diameter as the red +12V wire with
fuseholder. Use the in-line splice (20) to make the connection to the red +12V wire
with fuseholder (Figure 9). Trim off flush the stripped portion of the red wire. The
fuseholder should be in the vehicle cabin.
