SECTION 3: Installation Overview
The installation overview diagram below illustrates a properly installed Watchdog. This
overview is meant to help reference the general location of installed parts and pieces of the
Watchdog. Note that some fuse boxes will be located inside the cab of the vehicle and will
not require that the power wire go through the vehicle fire wall. For ease of installation,
look for an in cab fuse box before going through the fire wall.

SECTION 4: Installation
These installation instructions are split into four easy installation parts or activities. Each
part contains a small set of instructions to complete the part. Complete each part in order in
which they appear in this section for the easiest installation of this product. The installation
tasks start on the following page.
QUICK TIP: be sure that the switch on the OBD ll adapter plug is in the “down,” position. This will ensure
that the WatchDog is running o of power supplied from the power wire. The end result is that the Watch
Dog will only turn on when the ignition is turned on.

INSTALLATION
PART 1: CONNECT THE OBD ll ADAPTER TO THE VEHICLE OBD ll PORT
This part involves locating the vehicle’s OBD ll port and then simply plugging the OBD ll Adapter Plug
into the OBD ll port.
1. As the illustration below shows, OBD ll ports are always located somewhere under the drivers side
dash. The OBD ll port is a male receiver that will have the same shape as the end of the OBD ll Adaptor
plug.
2. Once the OBD ll port is located, then simply plug the OBD ll Adaptor plug into the OBD ll port.

INSTALLATION
PART 2: INSTALLING THE POWER WIRE
Part 2 involves locating the correct fuse within the vehicle fuse box, and connecting the power wire
from the OBD ll Adaptor plug to the fuse in the fuse box.
Pre Installation: Locate the vehicle fuse box; the vehicle owners manual will indicate where the fuse box is
located within the vehicle. Open the fuse box and identify a fuse that has “key on power.” To identify the correct
fuse, nd an accessory fuse using the fuse diagram in the vehicle owners manual. If the vehicle manual does
not help identify an accessory fuse use a voltage meter to identify a fuse that supplies power only when the key
is in the on position.
Installation:
1. See the diagram to the right, simply plug the end of the power wire into the OBD
ll block before running the opposite end to fuse box.
Quick Tip: For the cleanest install of the power wire to a fuse
location use a spade connector and a fuse tap even though you
could just stu the Power wire into the fuse hole.
2. Run the end of the wire to the location of the fuse box. It may be necessary to go through the re wall to get
to the fuse box, if this is the case it may be easier to run through an existing grommet rather than drilling a new
hole.
3. Prepare the end of the power wire by attaching a spade connector to the end of the wire.
4. Remove the selected fuse from its location and then place a fuse tap that is made for that size of fuse
into that selected fuse location along with the original fuse.
5. Connect the spade connector to the end of the fuse tap.
6. Use zip ties to secure any loose wire left hanging from excess slack in the power wire.

PART 3: RUN WATCHDOG MAIN WIRE HARNESS
In this section you will connect the Watchdog Main Harness to the OBD ll Adaptor and then run
the other end of the main harness up the side of the vehicle dash and connect it to the back of
the Watchdog.
1. Plug one end of the Main Harness into the Main Harness port on the OBD ll adapter plug.
2. Run the other end of the harness up through the vehicle dash on the driver’s side so that the
end of the harness emerges from the dash near the vehicle A-pillar. It may be necessary to temporarily remove the vehicle weather stripping and dash panel to achieve an installation where
the Main Harness cannot be seen when the driver’s door is opened.
3. Plug the Main Harness into the back side of the Watchdog, make sure that there is enough
slack in the main harness to accommodate mounting the Watchdog.

INSTALLATION
PART 4: MOUNTING THE WATCHDOG
The nal step to installation is mounting the Watchdog to the windshield using the universal
windshield mount.
1. Locate the T-shaped mount socket on the back side of
the Watchdog.
2. Notice that the top of the universal mount will t
into T-shaped socket and slide forward to secure the
Watchdog to the mount.
3. With the Watchdog connected to the mount use the
windshield mount to secure the Watchdog to the windshield. Be sure that the position of the Watchdog does
not obstruct the view of the road or distract the driver
from their primary responsibility, which is careful driving.
Also available is our 2 1/16” universal gauge mount.
Available on our website or through a Bully Dog Dealer.
