KIA 20-Pin to OBD2 16-Pin Adapter Cable

This adapter lets you connect the older 20-pin diagnostic connector found on KIA vehicles to a current-generation 16-pin OBD2 diagnostic tool. It is a purely passive adapter: it changes the connector shape and routes the useful pins through, so a modern scan tool can talk to an older vehicle — no electronics, no drivers, nothing to fail beyond the cable itself.

The cable is built for workshop use: flexible across a cold-rated temperature range, so the under-dash reach on a winter morning does not crack the jacket, and the passive routing covers the pins that KIA’s older interface shares with the OBD2 standard. One honest scope note: a passive adapter passes what the vehicle’s connector carries — coverage of specific systems depends on the vehicle and the scan tool, not on this cable.

FAQ

Which KIA years does it cover?
The 20-pin under-dash connector predates the standardised 16-pin port — match your vehicle’s connector shape to the photos before ordering.

Will every scan tool function work?
The adapter passes the pins the vehicle carries; system coverage depends on the vehicle protocol and the tool, as with any passive adapter.
