For all, who like to change the manuals of the steering wheel shifts (right English?) Right - high, Left - down (like AMG55):
1. cut the yellow cable of the left switch, and solder the cable coming from the switch onto the blue cable. The yellow cable coming out of the steering wheel please isolate.
Now cut the blue cable of the right switch and solder the end coming from the switch onto the yellow cable. Please isolate the cable coming out of the steering wheel.
Fix the switches - done!
