Connecting a telematics device to your vehicle often requires more than just plugging into the OBDII port. Variations in vehicle makes, models, and global manufacturing standards mean the OBDII port itself can differ. This is where an Obdii 16-pin To 9-pin Y-harness, among other harness types, plays a crucial role in ensuring a secure and reliable connection for your fleet tracking needs. This article will explore the different types of telematics harnesses, when they’re necessary, and best practices for installation.
When is a Telematics Harness Required?
While Geotab GO devices are designed to plug directly into a vehicle’s OBDII port, a harness becomes essential in several situations:
- Concealed Installation: To discreetly tuck away the telematics device, keeping it out of sight and protected from tampering.
- OBDII Port Availability: To free up the OBDII port for other uses, such as diagnostic scanning or connecting additional accessories like IOX Add-Ons.
- Compatibility with Older Systems: To bridge the gap between modern telematics devices and vehicles equipped with older 6-pin or 9-pin diagnostic ports, requiring an OBDII 16-pin to 9-pin Y-harness or similar adapter.
Types of Telematics Harnesses
Geotab offers a wide range of harnesses designed to accommodate the diverse landscape of vehicle connectors. Common diagnostic interface types include:
- OBDII 16-Pin: The standard for most modern vehicles.
- 6-Pin and 9-Pin: Frequently found in older models or specific heavy-duty vehicles. An OBDII 16-pin to 9-pin Y-harness is commonly used for these applications.
Geotab categorizes harnesses into five main types:
- OBDII Harnesses: For standard 16-pin OBDII ports.
- Deutsch Connector Harnesses: Primarily for heavy-duty vehicle applications.
- European Heavy Goods Harnesses: Specifically designed for the EU market.
- Custom Harnesses: Tailored for unique connection requirements, often involving multiple connection points, weatherproofing, or specialized global vehicle models.
- Special Order Harnesses: Available for specific applications upon request.
Geotab’s Universal Harness Kits
Simplifying installation, Geotab offers two universal kits:
- Universal OBDII T-Harness Kit (HRN-GS16K22): Includes a T-harness and 12 mounting adapters for various light, medium, and some heavy-duty vehicles globally.
- Universal Heavy-Duty T-Harness Kit (HRN-GS09K2): Includes a 9-pin T-harness and four mounting adapters, suitable for most international heavy-duty vehicles. This kit often includes an OBDII 16-pin to 9-pin Y-harness configuration for compatibility.
Maintaining Data Integrity with Telematics Harnesses
Proper connection is paramount for reliable data.
Do:
- Choose the correct harness for the specific vehicle and application. An OBDII 16-pin to 9-pin Y-harness is crucial for compatibility with 9-pin systems.
- Adhere to recommended installation procedures.
- Connect a straight harness to a T-harness for extended length when necessary.
Don’t:
- Connect two T-harnesses together.
- Exceed a total harness length of 2 meters (6.5 feet) to avoid data corruption and potential issues with the vehicle’s ECU.
Conclusion
Selecting the appropriate telematics harness, like an OBDII 16-pin to 9-pin Y-harness when needed, is crucial for successful telematics implementation. Geotab’s comprehensive range of harnesses and commitment to innovation ensure compatibility and reliable data capture for diverse fleet requirements. Consult Geotab’s resources for detailed harness selection and installation guidance.
