For Kawasaki Versys 650 owners looking to tap into their bike’s diagnostic data, connecting an OBD2 reader is surprisingly straightforward. Despite some online discussions suggesting complexity, the process becomes clear when you focus on the fundamentals. This guide will show you how to create your own Kawasaki Obd2 Adapter and access valuable information from your V650 using readily available tools and connectors.
Many OBD2 adapters are designed for cars and communicate using the KWP2000 (ISO9141) protocol, which is compatible with the Kawasaki V650. While pre-made cables might work, their compatibility isn’t guaranteed. To ensure a reliable connection, understanding the wiring and building a custom adapter is the most effective approach. With a background in electrical engineering and years of experience troubleshooting complex systems, we’ll break down the process to create a reliable kawasaki obd2 adapter for your V650.
Wiring Your Own Kawasaki OBD2 Adapter
The Kawasaki V650 utilizes a 4-pin connector located under the seat for diagnostics. This connector provides the necessary power and data lines for OBD2 communication. You’ll need to interface this with a standard 16-pin OBD2 connector, commonly found in cars, which will then connect to your OBD2 reader device.
V650 Diagnostic Connector Pinout
Looking at the V650’s diagnostic connector on the bike, with the key at the top and viewing it from the front, the pin assignments are as follows:
KLine GND
LLine VBAT- K-Line: Diagnostic communication line (often Pink/Blue or Purple/Violet wire on schematics)
- GND: Ground (Black/Yellow wire on the V650)
- L-Line: Less commonly used diagnostic line (Light Green/Black wire – optional connection)
- VBAT: Battery Voltage (Brown/White wire)

For the standard OBD2 connector (female), the pins you need to connect are:
- Pin 4 & 5: Ground (Connect to V650 GND)
- Pin 7: K-Line (Connect to V650 K-Line)
- Pin 16: 12V Battery Power (Connect to V650 VBAT)
- Pin 15: L-Line (Optional – Connect to V650 L-Line if your OBD2 connector has it available)

Step-by-Step Wiring Instructions
To build your kawasaki obd2 adapter, you will need:
- An OBD2 connector socket (female).
- A 4-pin connector compatible with the V650 diagnostic port (or you can carefully use individual wires).
- Wiring.
- Basic soldering or crimping tools.
Wiring Process:
- Ground Connection: Connect wires from OBD2 connector pins 4 and 5 to the GND pin on the V650 connector.
- K-Line Connection: Connect a wire from OBD2 connector pin 7 to the K-Line pin on the V650 connector.
- Power Connection: Connect a wire from OBD2 connector pin 16 to the VBAT pin on the V650 connector.
- (Optional) L-Line Connection: If your OBD2 connector has pin 15 and you wish to use the L-Line, connect a wire from OBD2 pin 15 to the L-Line pin on the V650 connector.

Conclusion
Creating your own kawasaki obd2 adapter is a rewarding DIY project that allows you to access your motorcycle’s diagnostic information. By understanding the pinouts and following these wiring steps, you can easily monitor your V650’s performance and health. This opens up a range of possibilities for maintenance, performance tuning, and a deeper understanding of your Kawasaki motorcycle. Remember to double-check your wiring and connections for a reliable and safe diagnostic experience.
