Illustration — use it to know where to look.

Location

Lower dashboard, to the left of the steering column, behind a small rectangular cover panel (approximately 14 x 8 cm) secured by two cross-head screws. The 16-pin OBD-II connector sits at the back of the recess, roughly in line with the driver's left knee. Same location on all Relay II body variants (Panel Van, Chassis Cab, Minibus).

How to access

Remove the rectangular cover panel by unscrewing two cross-head screws — a standard Phillips screwdriver is sufficient. Pull the panel away to expose the 16-pin connector recessed at the back of the cavity.
