This is a flat ribbon OBD2 splitter cable with one 16-pin male connector on one end and two 16-pin female connectors on the other. It plugs into the car’s OBD2 port and provides two active female ports, allowing two OBD2 devices to be connected and used simultaneously from a single vehicle port. The cable is approximately 30cm in total length, built in a flat ribbon format that sits flush and does not obstruct the driver’s footwell area.
What Problem It Solves
Most cars have a single OBD2 port. Owners who run more than one OBD2 device — a HUD display and a diagnostic scanner, for example, or a performance monitor alongside a code reader — have to unplug one device to use the other. Over time this causes wear on the vehicle’s OBD2 port, which is not designed for frequent plugging and unplugging cycles.
This splitter eliminates that problem. Both devices stay connected and both receive power and data from the OBD2 bus simultaneously. There is no need to swap cables or disconnect either device when switching between functions.
Installation Logic
Plug the male end of the splitter into the car’s OBD2 port — located under the dashboard on the driver’s side on most vehicles. Connect your OBD2 devices into the two female ports. That is the complete installation. No tools, no wire cutting, no modification to the vehicle required. The cable draws no power of its own and introduces no additional load on the OBD2 circuit beyond what the connected devices draw.
Behaviour Explanation
The splitter passes all 16 pins from the vehicle’s OBD2 port through to both female connectors simultaneously. Both connected devices receive the full OBD2 signal and power supply in parallel. Device behaviour — data polling, diagnostic functions, display output — is determined entirely by the devices connected, not by the splitter itself.
Note that some OBD2 devices may conflict if they attempt to communicate on the same PID simultaneously. In most everyday use cases — HUD display running alongside a passive monitor or code reader — this does not cause any issues. If you are running two active diagnostic tools simultaneously, confirm compatibility with your specific device combination before use.
Key Compatibility
Compatible with all vehicles fitted with a standard 16-pin OBD2 port. This covers the vast majority of Indian market cars — petrol vehicles from approximately 2005 onwards and diesel vehicles from approximately 2008 onwards. Also compatible with all standard OBD2 diagnostic tools, HUD displays, performance monitors, and code readers using the 16-pin interface.
Who Should Buy
Owners running two OBD2 devices simultaneously — such as a HUD display and a diagnostic tool, or a performance monitor alongside a code reader. Also useful for anyone whose OBD2 port is in an awkward position and wants the cable to provide better reach and access for connected devices.
Who Should Not Buy
It is not suitable for vehicles without a standard 16-pin OBD2 port. Also not intended for use with proprietary OBD connectors used on some older or non-standard vehicles. If you are unsure whether your car has a standard OBD2 port, verify before ordering.
FAQs
This OBD2 splitter cable carries a 6 month warranty. The return policy is exchange only.
Yes. Both female OBD2 ports on this splitter are active simultaneously, so two devices can be connected and used at once from a single vehicle OBD2 port.
In most everyday combinations, such as a HUD display running alongside a passive monitor or code reader, this works without issue since both devices simply receive the OBD2 signal and power in parallel. If you are running two active diagnostic tools that both try to communicate on the same PID at the same time, check compatibility with your specific device combination first, as conflicts are possible in that scenario.
It fits any vehicle with a standard 16-pin OBD2 port, which covers the vast majority of Indian market cars, generally petrol vehicles from around 2005 onwards and diesel vehicles from around 2008 onwards. It is not intended for vehicles using proprietary or non-standard OBD connectors.
No. It passes all 16 pins straight through from the vehicle’s OBD2 port to both female connectors, draws no power of its own, and adds no load to the OBD2 circuit beyond what your connected devices already draw.
The splitter is a flat ribbon cable approximately 30cm in total length, designed to sit flush in the footwell area without getting in the way.
No. It is plug and play: the male end plugs into your car’s OBD2 port and your devices plug into the two female ports, with no tools or vehicle modification required.
Yes, in the sense that it lets two devices stay connected simultaneously, avoiding the repeated plugging and unplugging of a single port that happens when you swap between two devices that each need direct access.
