The OBD2 L-Type Right Angle 1-to-2 Y-Splitter Extension Cable is a specialized diagnostic accessory that combines three essential functions in one cable: extension, splitting, and space-saving angled connection. This cable expands a single vehicle OBD2 diagnostic port into two separate female sockets, allowing simultaneous connection of two diagnostic devices while the 90° angled male connector ensures easy access in tight spaces .
This cable is designed for automotive professionals, fleet operators, and DIY enthusiasts who need to connect multiple devices—such as scan tools, code readers, GPS trackers, ELM327 interfaces, and data loggers—without constantly swapping cables . The L-type 90° male connector is particularly valuable for vehicles where the OBD2 port is recessed, blocked by trim, or located in a confined footwell area where standard straight connectors cannot fit comfortably .
Key Features
L-Type 90° Right Angle Male Connector
The standout feature of this cable is the 90° angled male connector that plugs into the vehicle's OBD2 port . This low-profile, space-saving design allows connection to OBD2 ports positioned in tight or recessed spaces where straight connectors cannot be inserted. The angle also reduces strain on both the vehicle's OBD port and the cable itself, minimizing the risk of damage over time.
1-to-2 Y-Splitter Configuration
The cable features a Y-shaped design with one 90° angled male connector on the vehicle side and two female connectors for connecting diagnostic devices . This allows you to:
- Connect a diagnostic scanner and a GPS tracker simultaneously
- Run a diagnostic tool alongside a data logger
- Install a performance monitor without losing access to the diagnostic port
- Power two OBD2 devices from a single vehicle port
Full 16-Core Pass-Through Connectivity
Unlike basic cables that only connect essential power and CAN lines, this splitter features all 16 pins fully wired with 16-core conductors . This ensures complete data and power transmission for all standard OBD2 protocols—including CAN bus, ISO9141, KWP2000, J1850 VPW, and PWM .
All 16 pins are fully connected through the cable .
12V/24V System Compatibility
Designed for standard automotive electrical systems, this splitter works reliably on 12V passenger vehicles and 24V light commercial vehicles . It supports the full voltage range required for OBD2 diagnostics and can power devices drawing standard current loads.
Durable Construction
Manufactured with high-quality materials for workshop and field durability :
- Copper or oxygen-free copper conductors for reliable signal integrity
- Heat-resistant PVC insulation (flame-retardant)
- Molded connectors with integral strain relief boots
- Resistant to heat, corrosion, and common workshop chemicals
Plug-and-Play Operation
No drivers, software, or installation required. Simply plug the L-type male connector into your vehicle's OBD2 diagnostic port (located under the dashboard) and connect your diagnostic devices to the female ports .
Technical Specifications
Cable Length Reference
Typical Applications
- Vehicle Diagnostics – Connect multiple scan tools, code readers, and diagnostic interfaces simultaneously
- GPS Tracking & Fleet Management – Install GPS trackers alongside diagnostic devices for continuous monitoring
- Performance Monitoring – Run data loggers and real-time monitors at the same time
- Port Protection – Reduce wear on vehicle's OBD2 socket from repeated tool insertion
- Development & Testing – Interface multiple development tools to the vehicle bus
- Memory Saver Use – Connect a memory saver while still using the OBD port for diagnostics
Important Note on Simultaneous Operation
The vehicle's ECU does not support two devices communicating simultaneously on the same data bus . While both devices can be physically connected, they cannot both request data at exactly the same time—this is a limitation of the communication protocol, not the cable itself. However, in practice:
- One device for live data display and the other for occasional gauge reading often works fine
- Passive devices such as power adapters or GPS trackers that only read data can operate simultaneously
- If you only need to power devices or read CAN data, both ports can be used concurrently
