Hi,
hoping for some advice, need this part for a c200 1998 mercedes, does anyone know if its a maindealer part only?

Also can anyone tell me how to fit it??? Are there any help guides for this anywhere. Recently found photos of how to fit the indicator/hazard switch to my audi on the internet and they were so good, only took 10mins to do, so thought you guys might do the same thing on here.

Many thanks
