Illustrative — for orientation only.
Driver's footwell, lower dash above the pedals on the door side. Standard 16-pin connector, no cover. On pre-facelift X200 cars (1999-2002) the port sits slightly higher and further inboard than on the 2003-onwards X204 — both versions are accessed without removing trim.
