Location

RHD (UK): driver's footwell, on the underside of the lower dashboard below the steering column, above the pedals and towards the bonnet release lever on the right. The 16-pin socket faces down, so feel for it with a torch in the footwell. LHD: same position mirrored - under the steering column above the pedals, near the bonnet release on the left. Same place on all SLK R172 models from SLK 200 to SLK 55 AMG.

How to access

Small plastic flap in the underside of the dash trim - prise it open with a fingernail, no tools and no trim removal. The connector is right behind it.
