2. Main Harness port: the main harness will plug into the GT and into this port during installation.
3. Power wire port: the power wire will run from this port to the vehicle fuse pox during instal-
lation. Plug into the GT and into this port during installation.
4. Power Supply Switch: use this switch to change power from running o of the Power Wire
to OBD ll power as a power supply for the GT.
5. Four Pin USB: This port is used if a Bully Dog pyrometer kit is purchased for the GT.

MICRO SD CARD
The Micro SD Card holds all of the elec-
tronic les necessary to properly start up
the GT, the SD card must be installed into
the micro SD card slot on the side of the
GT at all times.
UNIVERSALWINDSHIELD MOUNT

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.

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 thevehicle.
2. Open the fuse box and identify a fuse that has“key on power.”To identify the correct fuse, nd an
accessoryfuseusing thefusediagraminthe vehicleowners manual.Ifthevehiclemanualdoes not
helpidentify anaccessoryfuseuseavoltagemetertoidentifyafuse thatsuppliespoweronlywhen
the key is in the on position.
CONNECT THE POWERWIRE FROM THE 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. For a the cleanest install see our clean install instructions on the next page.

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
aspade connectortothe end ofthewire.
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.

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.Plugone endofthe MainHarness intothe MainHarness portonthe OBDlladapter plug.
2. Runthe other end oftheharnessup throughthe vehicledash on the driver’ssideso thattheend 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 can-
notbeseen.
3.Plugthe MainHarness intothe backsideofthe GT,make surethatthereis 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.
