Eliminate diagnostic port congestion with our purpose-built RP-1226 14-way splitter cable. It provides a reliable solution for connecting two diagnostic or telematics devices to a single vehicle’s RP-1226 14-way diagnostic port simultaneously.
Ideal for OEM integrators, telematics device manufacturers, and fleet solution providers, this harness ensures stable CAN Bus (J1939/J1708) communication and power distribution without signal interference.
Note: The RP-1226 14-way connector is commonly referred to as PR1226 or RP1226 in the industry.
How This RP-1226 14-Way Splitter Solves Fleet Connectivity Bottlenecks
Dual Connectivity: Creates two independent data channels from one vehicle port, enabling simultaneous device operation without manual swapping.
Signal Integrity: Incorporates full copper braided shielding and twisted-pair wiring specifically for CAN-H/CAN-L to prevent EMI/RFI noise and cross-talk.
Heavy-Duty Construction: Features injection-molded, high-temperature resistant PA66 housing and integrated strain relief rated for vibration & harsh environment endurance.
Rapid Deployment: No vehicle wiring modification required. Enables concurrent installation of ELD and GPS trackers, dash cams, or data loggers.
Full OEM Customization: We modify wire gauge, length, jacket color, connector branding, and pinouts to meet your exact specifications.

Frequently Asked Questions (FAQ)
Q1: Will using a splitter disrupt my truck’s CAN bus communication
A: This is a high-quality passive splitter cable. It is engineered with proper shielding and impedance matching to pass through CAN bus (J1939) and J1708 signals accurately to both output ports without causing conflicts, which is critical for dual-device operation.
Q2: Can I use this to connect an ELD and a GPS tracker at the same time?
A: Yes, this is one of the most common applications. The cable allows a mandated ELD and a secondary telematics device like a GPS tracker to share the diagnostic port’s power and data lines simultaneously.
Q3: My device uses a different connector. Can you customize it?
A: Absolutely. As a full-service factory, we routinely produce cables with mixed connectors (e.g., RP-1226 to OBD2, Deutsch, or custom interfaces). Provide your requirements, and we can engineer a solution.
Q4: What is the difference between this cable and your other 1-to-2 adapter?
A: This model features standard RP-1226 14-way female connectors on both outputs. For applications requiring a different output style or specific compatibility (e.g., with certain Freightliner integrations), please see our 14Pin RP-1226 1 Male to 2 Female Y Cable Adapter.
Q5: Do you provide samples for testing and qualification?
A: Yes, we provide sample units for OEMs and serious buyers to qualify. Contact us to discuss your sample needs and testing protocols.
Q6: What is your typical lead time for custom or bulk orders?
A: For standard configurations, lead time is 7-10 days. For fully customized or large bulk orders, lead time typically ranges from 2-4 weeks after final design confirmation.
Q7: How does this cable hold up against daily vibration and temperature swings in a truck cab?
A: Our cables are built for the heavy-duty lifecycle. We use automotive-grade materials, implement 5S workshop management, store components in climate-controlled warehouses, and subject products to vibration and temperature cycle testing.
Q8: Are the materials environmentally compliant?
A: Yes. We adhere to RoHS, REACH, and UL standards (where applicable). All plastics are full-plastic design and use compliant compounds.
Q9: Can you match a specific wire color code or add labeling?
A: Yes. Wire color coding, cable labeling, and printed logos are standard parts of our OEM/ODM service to match your assembly line requirements.
Q10: Where can I find more technical details about the RP1226 pinout and applications?
A: For an in-depth technical breakdown, including pinout diagrams, signal descriptions, and fleet application scenarios, please refer to our comprehensive guide: PR1226 14-Pin Splitter Cable: Complete Guide to Pinout, Specs & Applications.
