Full Product Description
Overview
The OBD2 L-Type Right Angle 1-to-3 Y-Splitter Extension Cable is a specialized diagnostic accessory that combines extension, three-way splitting, and space-saving angled connection in one cable. This cable expands a single vehicle OBD2 diagnostic port into three separate female sockets, allowing simultaneous connection of up to three 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, HUD displays, 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-3 Y-Splitter Configuration
The cable features a Y-shaped design with one 90° angled male connector on the vehicle side and three female connectors for connecting diagnostic devices. This allows you to:
- Connect a diagnostic scanner, GPS tracker, and HUD display simultaneously
- Run a diagnostic tool alongside multiple data loggers
- Install performance monitors without losing access to the diagnostic port
- Power up to three OBD2 devices from a single vehicle port
Full 16-Pin Pass-Through Connectivity
This splitter features all 16 pins fully wired, ensuring 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.
Durable Construction
Manufactured with high-quality materials for workshop and field durability:
- Copper conductors for reliable signal integrity
- Heat-resistant PVC or TPE insulation (flame-retardant)
- Molded connectors with integral strain relief
- Resistant to heat, corrosion, gas, oil, and common workshop chemicals
Optional Individual Power Switches
Some variants of this cable feature individual ON/OFF power switches on each female port, allowing you to power off unused devices to prevent battery drain.
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.

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
- HUD and Accessories – Connect heads-up displays and car chargers alongside diagnostic tools
- Port Protection – Reduce wear on vehicle's OBD2 socket from repeated tool insertion
- Development & Testing – Interface multiple development tools to the vehicle bus
Important Note on Simultaneous Operation
The vehicle's ECU does not support two devices communicating simultaneously on the same data bus in most cases. While multiple devices can be physically connected, they cannot all 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 another for occasional gauge reading often works fine
- Passive devices such as power adapters or GPS trackers that only read data can operate simultaneously
- The cable is engineered to ensure stable power and data flow to all three ports, preventing interference between devices
Power Switch Models: For applications where devices may continue drawing power when the vehicle is off, models with individual power switches allow you to turn off unused ports and prevent battery drain.
