I have a w204 c250 cgi fully optioned. However I just noticed that the interior fuse box was never fitted in the factory. very surprising discovery given tha fact that the car is fully optioned.

I just installed illuminated door sills to my car and I noticed that I am lacking the interior fuse box next to the steering wheel to attach the fuse from the illuminated door sills.

Rather than attaching the wire elsewhere I decided to purchase the fusebox,(it only costs 20 pounds) and retrofit it to my car. However I have a question.

Is there a wiring harness that connects the interior fuse box to the front SAM? If not, does anyone have a part number to order this wiring harness? Otherwise is it too difficult to fabricate one? i think it is only one live wire.

Anyone expert that can help me out or any w204 owner that already has the interior fuse box and can check the wiring harness and give me some advice?

Thank you
