DB9 4-Head to OBD2 16-Pin Adapter Cable, 0.3 m

This adapter cable connects diagnostic tools with a DB9 four-head interface to the standard OBD2 16-pin vehicle port — the bridge for the many popular scan tools that terminate in a DB9 rather than a J1962 plug.

Build data: 0.3 m lead, 150 g, working temperature −30 to +80 °C, materials compliant with the RoHS standard. The four-head DB9 format matches the pin-assignment convention of DB9-based tools — if your tool uses a different DB9 pin map, see the FAQ.

One honest scope note that runs across this whole family: a passive adapter changes the connector and routes the pins that the tool’s pin map assigns to OBD2 — it does not add protocols. Which systems a scan tool actually reads depends on the vehicle and the tool software, not on this cable.

FAQ

My DB9 tool has a different pin map — will this work?
DB9 diagnostic pin maps vary by tool family. Match the 4-head convention your tool documents, or send the pinout and we confirm the variant before you order.

Why “4-head”?
It describes the moulded four-screw DB9 hood format used by the common tool leads — the mechanical fit your tool expects.
