Autel 3-in-1 OBD2 Adapter Cable — 16-pin to 6/4/3-pin OBD1 Converter for Motorcycles, Plug-and-Play

The Autel Original 3-in-1 OBD2 Adapter Cable converts a 16-pin OBDII diagnostic plug into 6-, 4-, or 3-pin OBD1 connectors so many newer European motorcycles and select vehicles can communicate with standard OBD-II scanners.

This Autel adapter is a compact, plug-and-play wiring solution designed to bridge older or model-specific diagnostic ports to a universal 16-pin OBDII interface. It’s intended for technicians, home mechanics, and riders who need to connect a generic OBD-II reader or compatible diagnostic tool to bikes and some vehicles that use 6-, 4- or 3-pin OBD-style connectors. The cable itself is a passive converter—it routes signals between a 22-pin/OBD1-style plug and a standard 16-pin OBDII socket and does not supply power or perform scanning functions.

Which motorcycles and vehicles work with this Autel adapter?

The adapter fits certain later-model European motorcycles and selected makes that use small OBD-style connectors instead of a full 16-pin port. Compatibility is model- and year-dependent, so you should verify your bike’s diagnostic connector type before purchasing.

• Common fits: Moto Guzzi, Piaggio, Vespa and some Yamaha and Honda models among later production years.
• Typical years covered: many units from 2016 onward, but not every year or trim.
• Not universal: always confirm connector pinout and protocol with your user manual or Autel support.

How do I use the cable with my OBD-II scanner?

Using the cable is straightforward: match the correct small-pin plug (6, 4, or 3 pin) to your vehicle’s diagnostic socket, then attach your OBD-II scanner to the 16-pin connector. The adapter is passive and requires a compatible scanner that supports the vehicle’s protocol.

• Plug the small connector into the motorcycle or vehicle diagnostic port firmly.
• Attach your OBD-II scanner to the 16-pin socket — no tools or wiring changes needed.
• Power and scanning functions depend on your scanner and vehicle ECU; the cable only routes signals.

What can I expect in terms of build quality and durability?

Autel manufactures this adapter to OE-style standards for reliable signal transmission and repeated use. The cable uses durable materials and factory quality control to resist wear and maintain stable data transfer over time.

• Rated for sustained use — designed to withstand thousands of plug cycles.
• Robust insulation and secure molded connectors reduce accidental damage.
• Strict factory QC helps ensure consistent pin mapping and signal accuracy.

Does this adapter include warranty or support?

Yes — the product is backed by Autel support and a limited warranty. If you need help confirming compatibility or encounter issues, Autel customer service is the recommended contact channel.

• 1-year warranty coverage for manufacturing faults.
• 30-day no-reason returns for buyer peace of mind.
• Direct support: contact Autelonline@outlook.com for compatibility checks and troubleshooting.

Who is this for: The Autel Original 3-in-1 OBD2 Adapter Cable is aimed at motorcycle owners, independent mechanics, and professional technicians who need a simple, high-quality way to connect universal OBD-II diagnostic tools to small-pin diagnostic ports on many newer European bikes and select vehicles. It’s ideal when you have a compatible scanner but your bike uses a 6-, 4- or 3-pin diagnostic connector and you want a reliable, OEM-quality link without modifying the vehicle’s wiring. Note: confirm your bike’s connector and protocol before purchasing; the cable does not act as a scanner or supply power.
