Honda 3-Pin to 16-Pin OBD2 Diagnostic Adapter Cable

Honda used a compact 3-pin diagnostic connector on a generation of vehicles before the 16-pin J1962 standard took over. The scanner in your toolbox is 16-pin; the car under the bonnet is 3-pin. This adapter closes the gap: the 3-pin end seats into the Honda connector, the 16-pin end takes any standard OBD2 diagnostic tool, and the scanner reads the vehicle through the mapped pins.

High-quality materials give the cable superior flexibility and durability — the build quality that matters in an adapter that gets borrowed, coiled, dropped in the tool drawer and asked to work again tomorrow. Compatible with diagnostic tools having a 16-pin socket; the adapter only carries the connection, your scanner handles the protocol.

Key features

• Honda 3-pin interface to standard 16-pin OBD2 tool
• Connects OBDII interface diagnostic tools to older Hondas
• Compatible with diagnostic tools having a 16-pin socket
• Superior flexibility and durability from quality materials

Specifications

An honest note: check which diagnostic connector your Honda actually carries before ordering — the 3-pin plug sits on specific model years, and later vehicles use the standard 16-pin port directly with no adapter needed. Protocol coverage for the vehicle’s era depends on your scanner’s supported standards.

Typical applications

• Workshops serving older Honda model generations
• Used-car inspection where vehicle age varies widely
• Universal diagnostic kits kept ready for pre-standard vehicles
• Matching adapters for other legacy brands to build a full workshop set

Stored between jobs, the adapter takes no more room than a coiled charging lead — which is the point: coverage for the legacy generation without dedicating a second scanner to it.
