Key Features
Route Three Sockets from Each of Two Cables
1-to-3 OBD2 Splitter Cable
Splits one vehicle OBD2 port into three OBD2 female ports, making it easier to connect compatible OBD2 tools and accessories.
All 16 Pins Connected
The 16-pin design follows the standard OBD2 port layout and keeps all 16 pins connected for normal OBD2 extension use.
No Wire Cutting
Plug-in installation does not require cutting or modifying the original vehicle circuit, helping protect the original car wiring.
Flexible TPE Cable
The soft plastic outer case and environmentally friendly TPE material make the cable flexible, durable, and easier to route inside the vehicle.
Copper Core Wire
High-quality copper core wire supports faster and more stable signal transmission for compatible OBD2 communication devices.
Heavy-Duty Craftsmanship
Heavy-duty materials and quality craftsmanship give the cable better flexibility, longer service life, and stronger daily-use durability.
No Wire Cutting
The adapter extends the original diagnostic port through a plug-in connection, with no cutting or modification of vehicle wiring.
Two 50 cm 1-to-3 Splitters
The 50cm cable connects one J1962 male plug to three female sockets with all 16 pins connected, for compatible 12V vehicle diagnostic setups.
OBD2 Diagnostic Access
Helps connect compatible OBD2 diagnostic tools without repeatedly reaching into a tight original port area.
OBD Accessory Extension
Useful for extending the OBD2 connection point for compatible OBD accessories and in-car devices.
Diagnostic and Accessory Routing
Supports quick plug-and-play testing in maintenance, inspection, and workshop environments.
In-Car Installation
The 50cm cable and flexible case help route the connector more conveniently inside the vehicle cabin.
Passive OBD2 Port Splitter
Routes one 16-pin vehicle connection to three female sockets without protocol conversion; every socket shares the vehicle’s power and communication lines.
Shared-Port Limits
Connect multiple devices only after confirming their combined current draw and communication behavior are compatible, because all three sockets share the vehicle’s power and data lines.
12V Connection Environment
The listed voltage is 12V, making the cable suitable for standard 12V automotive OBD2 connection environments.
Multi-Device Communication Limits
Multiple devices can be connected physically, but simultaneous communication is not guaranteed and may be disrupted by device conflicts.
Preserve Original Wiring
Do not cut or modify the vehicle’s original OBD wiring when using this splitter.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
How to Use
Connect, Route and Check Communication
Confirm The Vehicle Port
Identify the exact vehicle connector, year, and pinout; inspect it for damage.
Confirm The Tool Chain
Verify the scanner, software, protocol, module, task, and any authorization independently of the cable.
Connect Safely
Follow the vehicle and tool procedure, align connectors correctly, and never force a mismatched plug.
Route Without Strain
Position the cable away from pedals, sharp edges, heat, moving parts, and pinched trim.
Verify Communication
Run the intended read-only connection check first. If communication changes, remove added devices or the extension and compare direct connection.
Safety & Compatibility
Check Pin Fit, Routing and Power Limits
Passive Hardware
Splits and extends the physical OBD2 connection while the connected tools provide diagnostic functions.
Pinout And Fit
Match the connectors and pinout to the vehicle port and diagnostic tools before connection.
Vehicle Movement
Keep all cable and device parts clear of pedals, steering, seat tracks, doors, and driving controls.
Shared Power
Do not attach unknown or high-current devices to vehicle diagnostic power. All connected devices share the port supply.
Disconnect If Unstable
If a tool drops connection, overheats, resets, or changes vehicle behavior, stop and return to a known direct connection.

FAQs
Connector, Fit and Function Questions
What Is The AUTOOL OBD2 Splitter Cable Used For?
It is used to extend one vehicle OBD2 port into three OBD2 female ports. This makes it easier to connect compatible OBD2 diagnostic tools, OBD accessories, data devices, or in-car OBD equipment without cutting the original vehicle wiring.
Will This Cable Fit My Vehicle?
The cable is designed for vehicles with a standard OBD2 protocol port. Check that your vehicle has a standard OBD2 connector before ordering, and do not force the connector into a non-standard or damaged port.
Are All 16 Pins Connected?
Yes. All 16 pins are connected in the international-standard OBD 16-pin layout.
Can I Connect Multiple OBD2 Devices At The Same Time?
The splitter provides three OBD2 female ports and can help connect more than one compatible device. Actual simultaneous communication depends on your vehicle, OBD protocol, and the connected devices. If two devices conflict, disconnect one device and test again.
Does Installation Require Cutting The Original Car Circuit?
No. The cable is designed for plug-and-play, non-destructive installation. It does not require wire cutting and does not need modification of the original car circuit.
What Is The Cable Length?
The listed cable length is 50cm. The flexible cable helps route the connector more conveniently inside the vehicle cabin or workshop testing area.
What Materials Are Used?
The listed material information includes nickel pin connector details, high-quality copper core wire, and environmentally friendly TPE outer material. The soft plastic case is designed to be flexible, durable, and longer lasting.
What Is Included In The Package?
The package includes 2 OBD2 splitter Y cables. No diagnostic scanner, OBD display, GPS tracker, or other OBD device is included.
Can I Use High-Current OBD Accessories With This Splitter?
Avoid connecting incompatible or high-current accessories through the splitter. Use compatible OBD2 devices and check the instructions of each connected device before long-term use.
Who Should I Contact For Wholesale Purchase Or Compatibility Confirmation?
Contact AUTOOL Store support for wholesale purchase, vehicle compatibility checks, OBD2 accessory confirmation, warranty support, and after-sales questions.
Does This Cable Add Diagnostic Functions?
No. It only changes reach, routing, connector shape, or socket count. Available functions depend on the vehicle, pinout, scanner, software, protocol, and authorization.
Will Every Connected Device Work At The Same Time?
Not necessarily. Devices share power and communication lines and can conflict. Confirm current demand and protocol behavior, then disconnect one device if communication becomes unstable.
