AUTOOL 3-WAY SPLITTER · 16-PIN TRIPLE OBD2 EXTENSION
AUTOOL OBD2 3-Way Splitter 35cm Extension Cable (1 Male to 3 Female)
Keep two permanent OBD2 accessories installed under the dash while reserving a dedicated third 16-pin port for workshop diagnostics or oscilloscope probing.
- 1 Male -> 3 Female
- 35 cm Pure Copper
- All 16 Pins Active
Engineered for Professional Workshop Demands
The AUTOOL OBD2 3-Way Splitter 35cm is built to deliver speed, accuracy, and durability in busy service bays.
Three Independent 16-Pin Female Outputs
Run a GPS tracker on port 1 and a HUD or LPG controller on port 2, while leaving port 3 open for your diagnostic scanner.
Full 16-Pin 1:1 Pure Copper Parallel Bridge
Every pin from 1 to 16 is connected across all three female sockets using oxygen-free copper cores for zero signal loss.
Essential for ECU Bench Testing Rigs
Connect a diagnostic scanner, a CAN-Bus analyzer, and an oscilloscope simultaneously to a single ECU bench harness.
35cm Flame-Retardant Flexible TPE Jacket
Reinforced molded Y-junctions and oil-resistant TPE insulation withstand daily workshop flexing.
TRIPLE PORT EXPANSION
Manage GPS, Telemetry & Diagnostic Scanners Without Unplugging
Fleet vehicles often run both a telematics tracker and an auxiliary OBD module. The AUTOOL 3-way splitter keeps both hidden behind the dash while providing a clean third service port.
- Supports 2 permanent modules + 1 open diagnostic port
- Protects the factory vehicle OBD2 socket from mechanical damage
- Separate branch spacing accommodates wide VCI dongles
ECU BENCH & SCOPE READY
Three-Way Access for Advanced Electrical Diagnostics
In ECU repair labs, technicians can communicate with the module on port 1, monitor power consumption on port 2, and capture CAN High/Low frames on port 3.
- Full 16-pin wiring supports CAN, K-Line, J1850, and OEM pins
- Heavy-gauge power and ground lines handle multi-device loads
- Snug J1962 female sockets hold heavy VCI heads securely
INDUSTRIAL BUILD QUALITY
35cm Low-Reflection Length & Molded Strain Relief
Short 35cm branches prevent CAN-Bus impedance mismatches while reinforced strain-relief boots protect against pull stress.
- Safe for both 12V passenger vehicles and 24V heavy-duty trucks
- Corrosion-resistant plated pins rated for 5,000+ cycles
- Backed by a 6-month official Otoeko warranty

Workshop Application & Operating Guide
Recommended 4-step standard operating procedure for accurate results.
Connect Male Plug to Vehicle
Insert the 16-pin male connector into the vehicle's OBD2 socket or bench harness.
Attach Permanent Accessories
Plug your GPS tracker and secondary module into female ports 1 and 2.
Keep Port 3 Open for Service
Use the third female socket for diagnostic scanners or oscilloscope probes.
Communication Guideline
Passive monitors and power devices run simultaneously; do not run two active diagnostic scan tools polling the ECU at the same time.
Conventional Methods vs. Professional Diagnostics
How precision engineering eliminates guesswork and comebacks.
Conventional / Basic Methods
- 2-way splitters run out of ports when both GPS and HUD/LPG are installed
- Partial-pin cables fail to read manufacturer-specific ECUs
- Weak splice joints fail under dashboard vibration
- Overly long cables create pedal hazards and signal noise
