Autel Original OBD2 16 Pin OBDII Y Splitter Extension

When you need to connect two diagnostic tools, a telematics dongle and a scanner, or a performance monitor and a code reader at the same time, swapping devices becomes inconvenient and slow. This Autel original OBD2 Y-extension is made to extend your vehicle's single OBDII Data Link Connector (DLC) into two female 16-pin sockets while keeping signal integrity and physical durability. It's a compact, plug-and-play solution that preserves access to power and data without splicing or adapters.

How reliable is the signal and data transmission with the splitter?

The cable uses high-purity oxygen-free copper conductors and a robust internal core to reduce resistance and maintain quick data exchange. Design choices like a thickened wire core and one-piece molding help the cable resist wear and preserve connection quality over time.

• High-purity oxygen-free copper for low-loss transmission
• Thickened internal core improves tensile strength and durability
• One-piece molded connectors and secure shielding to reduce interference

Will this Y splitter work with my OBDII-equipped car and tools?

Yes — the Autel splitter is compatible with all standard OBDII 16-pin vehicle ports and diagnostic devices designed for that interface. It simply plugs into the vehicle DLC and provides two female 16-pin outputs, allowing two OBDII-compatible tools to be attached simultaneously.

• Fits standard 16-pin OBDII vehicle ports (DLC)
• Works with scanners, dongles, code readers, and telematics modules
• Plug-and-play — no configuration or wiring changes required

How long is the cable and is it sturdy enough for workshop use?

The extension provides approximately one foot of length from the male plug to the Y split, offering modest reach to position devices near the dash or under it. Construction focuses on shop-grade resilience: reinforced joints, braided tail protection, and a design that minimizes stress at the connector points.

• About 1 ft extension length for convenient access
• Double fishnet (braided) tail design for abrasion resistance
• Reinforced connector molding to prevent breakage in repeated use

What safety and service assurances come with the Autel splitter?

Autel backs this original accessory with its customer-first policies and post-sale support. The cable arrives ready to use and is covered by Autel’s listed warranty and return options to reduce buyer risk.

• 1-year warranty and 30-day return/replace policy
• Lifetime technical support from Autel's service team
• Direct customer contact available via Autel support channels

Who this is for: The Autel OBD2 16-pin Y splitter extension is ideal for professional technicians, fleet managers, and DIY enthusiasts who frequently need two simultaneous OBDII connections — for example, running a persistent telematics device while scanning live data with a diagnostic tool. It also suits workshop environments where convenience and reduced connector swapping speed up diagnostics and testing workflows.
