Since various programs, tools, parts and techniques are used for the vehicle maintenance
and different operators may have different operations, due to various kinds of diagnostics
compliers, the manual cannot predict every situation and provide related safety
suggestions.
Vehicle service technicians are in charge of fully learning about the system under tests,
and applying appropriate repairing approaches and testing programs.
When conducting tests, it’s necessary to apply proper operations to avoid personal
safety risks to yourself and other people inside the working area and prevent damages to
the equipment in use or vehicles under tests.
Before starting to use the equipment, please refer to and observe the safety information
provided by the vehicle or equipment manufacturer and applicable testing programs.
Please
use the equipment according to the Operation Manual, read, understand, and observe all
safety information and instructions included in this manual.

3
ventilated since the vehicle exhaust is harmful to human bodies.
◆ Wear goggles that meet the ANSI standard
◆ Set the gear to P (auto) or N (manual) and guarantee the parking brake is enabled
(hand brake pulled)
◆ Make sure your clothes, hair, hands, and tools stay away from the operating engine
parts or hot engine parts
◆ Place bricks before each wheel to prevent the vehicle from moving accidentally
◆ The vehicle must be attended during testing and operating
◆ Pay special attention when working around the ignition coil, distributor cap, ignition
wire, and ignition plug for that these parts can generate dangerous voltages
◆ Make sure fire extinguishers suitable for the gas/chemicals/are electrical provided
at the site
◆ Do not plug or unplug the equipment when the ignition switch is on or the engine is
working
◆ Keep the equipment dry, clean, and avoid touching oil, water or grease. Use a

GODIAG GT108 Super OBDI-OBDII universal conversion adapter can convert the OBDI diagnostic
interface of cars, trucks, tractors, mining vehicles, generators, boats, motorcycles, individual ECU
control units, etc. into standard OBDII diagnostic interfaces through DIY wiring Interface,
convenient for car maintenance personnel to connect to OBDII diagnostic programming
equipment for data streams reading, fault codes diagnosis, programming, activation and coding...
Product Features:
1. DIY wiring, it can be converted to OBDII according to the car diagnostic interface. [Because the
definitions of diagnostic interfaces in different regions are inconsistent, the popular conversion
cables and adapters in the market cannot use different definitions of diagnostic interfaces.
GODIAG GT108 Super OBDI-OBDII can be used by maintenance engineers to connect according to
their own needs]
2. The device has reverse connection protection. (If the power supply is connected wrong, the
device will not burn out, and it will not cause harm to the OBDII diagnostic programming device.)
3. Independent GND4, GND5. (It is more suitable for judging the problem of poor grounding of
some control units.)
4. Analog IGN switch. (Press the IGN switch, the corresponding port outputs ING VCC)
5. Power indicator, GND4, GND5 switching indicator, IGN switching indicator.
6. DIY the way to lock the wire. Equipped with different diagnostic interface cables, ECU cables,
and locking screwdrivers.
7. Truck wiring kit, car and motorcycle wiring kit, (Different configurations of wiring kits are
different, please purchase according to maintenance needs.)

5. How to Use GT108

Steps:
1. Find the definition of the diagnostic interface (find the maintenance manual of your own vehicle, or
search online.), or see the definition diagram of the corresponding diagnostic interface of the GT108
manual.
2. According to the interface definition, find out the connection line needed by your car, and connect
to the GT108 adapter according to the definition. (Use a screwdriver to lock the terminal.)
3. Connect the connected diagnostic cable to the vehicle OBD1 diagnostic interface according to the
definition. (Connect GND 4 or GND5 first, and then connect BAT+. If the power cable is connected
correctly, the POW light of the GT108 host will light up. If the vehicle diagnostic interface does not
have power, please connect the car battery to the DC power connector of GT108 with the battery
cable. If the vehicle needs the ignition signal, connect the O-IGN line, and press the IGN switch, the
corresponding IGN light will light up, and the O-IGN line will output the ignition power signal.)
4. Connect the communication line CAN or K-line to the diagnostic interface. (Note: If it is the truck
diagnostic software added by the car diagnostic equipment, you need to buy a GT106 24V to 12V
adapter.)
5. Connect the diagnostic device to start diagnosing the vehicle.
Note: If you cannot find the definition for your own vehicle diagnostic interface, you can first find out the
power supply of the diagnostic interface. First use the black battery clip on the battery connection cable to
connect the negative pole of the battery, and then use the BAT+ line to connect to the diagnostic interface
to find the power supply. You can also use a multimeter to find the diagnostic interface power supply. The
definition of the diagnostic interface can also be judged by the GT101 Pirt Electric Circuit Tester device.
