I have a 1993 124.028 sedan. I recently replaced the combination switch because of a malfunctioning wiper. The new combination switch came from peach parts and had all the same markings and multipoint connection except for a small doughnut wire which I didn't connect. When I got everything back together everything functioned as it should except for the horn. I'll try to get a photo of the connection up ASAP. Any help would be greatly appreciated.
