Autel OBD2 16-Pin Y Splitter Extension Cable 1ft (30cm) — Dual OBD-II Ports, Durable Molded Connectors

The Autel OBD2 16-pin Y splitter extension cable turns a single vehicle OBD-II port into two full 16-pin connectors, letting you plug in two diagnostic devices at once without removing the original harness.

Designed for technicians, enthusiasts and fleets, this compact 1-foot (30 cm) Autel adapter lets you extend and duplicate the OBD-II connector quickly. Built with durable conductors and molded housings, it supports standard 16-pin OBDII devices and ensures stable signaling for simultaneous tool operation. It’s a simple, plug-and-play solution when you need to run a scanner and a telematics device, or to compare two tools side-by-side while diagnosing a vehicle.

How does this splitter maintain reliable data transfer when two devices are connected?

The cable uses high-purity oxygen-free copper conductors and reinforced wiring to minimize signal loss and interference. Its one-piece molded connector and braided strain relief reduce the chance of breaks or intermittent contacts.

• Oxygen-free copper core for low resistance and fast signaling
• Thickened internal wires for better tensile strength
• Double braided tail and one-piece molding to prevent connector fatigue

Will this work with every car that has an OBD-II port?

Yes — the Autel 16-pin Y splitter follows the standard OBD-II 16-pin layout, so it can be used on vehicles equipped with a compliant OBDII DLC. It is protocol-agnostic and designed to accept any diagnostic tool that fits the 16-pin socket.

• Compatible with all standard 16-pin OBD-II vehicle ports
• Accepts most scan tools, code readers, and telematics or logging devices
• Ideal for bench testing or in-vehicle simultaneous connections

How easy is it to install and remove in everyday use?

Installation is literally plug-and-play: connect the male end to the vehicle’s DLC and attach up to two diagnostic devices to the female outlets. The compact 1ft length keeps connectors close to the dash for neat setup while remaining long enough for typical tool placement.

• One-foot length balances reach and convenience
• Firm molded plugs for secure, wobble-free connections
• No drivers or configuration required — instant operation

What protections and support does Autel provide with this cable?

The adapter is built to withstand routine workshop use with reinforced conductors and robust housing. Autel backs the product with a customer-first policy including warranty and support to address defects or compatibility concerns.

• Durable construction for repeated connect/disconnect cycles
• Customer support plus limited warranty and return policy
• Designed by an established automotive tool brand for peace of mind

Who is this for? This Autel 16-pin OBD2 Y splitter extension is ideal for professional mechanics, mobile technicians, fleet managers, and DIY vehicle owners who need to run two OBD-II devices concurrently — for example, comparing scanners, combining a diagnostic tool with a telematics unit, or keeping a live logger connected while performing tests. If you need a reliable, short-length adapter that preserves signal integrity and simplifies multi-tool workflows, this compact Autel cable is a practical addition to your toolkit.
