SECTION 3:Installation Overview
The installation overview illustrates a properly installed GT. This overview is meant to help refer-
ence the general location of installed parts and pieces of the GT. 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 re wall.

INSTALLATION
SECTION 4:Installation
These installation instructions are split into ve Easy Steps. Follow the steps for the easi-
est installation of this product.
STEP 1:CONNECT THE OBD ll ADAPTER TO THE VEHICLE OBD ll PORT
This step 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.
OBDll Port Location
All OBDll ports are located under the
dash on the drivers side of the vehicle.

INSTALLATION
STEP 2: CONNECT THE POWER WIRE TO THE VEHICLE FUSE BOX
Step two 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.
IDENTIFYTHE CORRECT FUSE:
1. Locate the vehicle fuse box; the vehicle owners manual will indicate where the fuse box is located
within the vehicle.
2. 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.
CONNECT THE POWER WIRE FROMTHE OBD II BLOCKTOTHE CORRECT VEHICLE FUSE:
1. Connect the power wire to the power wire port on the OBD ll Adaptor plug.
2. Run the raw end of the power wire to the vehicle fuse box, in many cases this will mean taking the
power wire through the vehicle re wall. On most vehicles the power wire can run through an exist-
ing port, it is not necessary to drill.
3. Remove the correct fuse from the fuse box and plug the fuse back into its original location along
with the power wire.

INSTALLATION
FOR A CLEAN INSTALL INTO THE FUSE LOCATIONS:
There are multiple dierent fuse types in OEM vehicles. For a clean install, use a fuse tap and
spade connector that will work with the specic fuse being used for this install.
1. Once the end of the power wire is near the fuse box, prepare the end of the power wire by attaching
a spade connector to the end of the wire.
2. Remove the correct fuse from its location and then replace that fuse with a fuse tap that is made
for that size of fuse.
3. Connect the spade connect to the end of the fuse tap.
4. Use zip ties to secure any loose wire left hanging from excess slack in the power wire.

INSTALLATION
STEP 3: RUN GT MAIN WIRE HARNESS
In this section you will connect the GT Main Harness to the OBD ll Adaptor plug 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 GT.
1. Plug one end of the Main Harness into the Main Harness port on the OBD ll adapter plug.
2. Runtheotherend of the harnessupthroughthevehicledashonthe driver’s sideso thatthe endof 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 can-
not be seen.
3. Plug the Main Harness into the back side of the GT, make sure that there is enough slack in the main
harness to accommodate mounting the GT to the windshield.

SECTION 5:Mounting the GT using theWindshield mount
The final step to installation is mounting the GT to the windshield using the univer-
sal windshield mount.
1. Locate the T-shaped mount socket on the back
side of the GT.
2. Notice that the top of the universal mount will t
into T-shaped socket and slide forward to secure
the GT to the mount.
3. With the GT connected to the mount use the
windshield mount to secure the GT to the wind-
shield. Be sure that the position of the GT does
not obstruct the view of the road or distract the
driver from their primary responsibility, which is
driving responsible.
