Our take on the OBD Adapter Cable 6-Pin and 3-4 Pin to OBD 16-Pin Black

This is a diagnostic adapter cable that links older, vehicle-specific diagnostic connectors to a standard OBD-II 16-pin scanner. One end carries a 6-pin plug and a 3+4 pin plug; the other ends in the familiar 16-pin OBD-II connector. It suits home mechanics and shops working on older vehicles whose ports predate OBD-II, letting one scan tool serve both. Unlike a single-plug adapter, it covers two legacy connector types in one cable, but it is a passive pass-through: it changes the plug shape, not the protocol, so the scanner must still support the vehicle.

  • Heavy-duty cable with secure connectors
  • Plug-and-play, no wiring or soldering
  • Length gives comfortable reach to awkward ports

  • Bulky twin-plug end can be tight in cramped footwells

Questions and answers

Will this let my OBD-II scanner read an older car?
Only if your scanner supports that vehicle's diagnostic protocol. The cable just adapts the plug shape from 6-pin or 3+4 pin to 16-pin; it does not translate or add protocols.
Which vehicles use 6-pin or 3+4 pin diagnostic ports?
Mostly older European and Asian models from before OBD-II became standard. Check your car's port shape against the two plugs before buying.
Do I need a special scanner for these ports?
You need a scanner that lists support for the older protocol your car uses. Many pro-grade tools do; basic code readers often do not.
Is it plug-and-play?
Yes. Plug the matching end into the car's port and the 16-pin end into your scanner. No wiring or soldering.
Does it work for both connector types at once?
No. Use the 6-pin plug or the 3+4 pin plug, whichever matches your vehicle's port, and leave the other unconnected.
Where is the OBD Adapter Cable 6-Pin and 3-4 Pin to OBD 16-Pin Black cheapest?
At Newegg, for $22.69, as of our latest check.
