Illustration — use it to know where to look.

Location

RHD (UK): Driver's footwell, low down beneath the steering column, tucked into the side of the cabin fuse box housing on the right. The 16-pin connector sits inside the fuse box assembly rather than out in the open, just above the pedals. LHD: Same arrangement mirrored to the left of the steering column, inside the cabin fuse box housing on the driver's side. Location is consistent across all Mk2 trims.

How to access

There is a clip-on plastic cover over the fuse box/socket area. Prise it off starting at one corner (it releases on a few clips) by hand, no tools needed. The 16-pin socket is recessed inside next to the fuse bank, so reach in slightly once the cover is off.
