Comfort system turn signal flashing

A2.1.4.2

That is especially convenient when passing: Lane changes as well as the return into the line of cars is clearly announced by the repeated use of turn signals, as the German Highway Code (STVO) calls for in §5. The vehicles behind receive sufficient warning, and the passing driver can fully concentrate on the flow of traffic. This "blinking sequence" is a comfort feature that is absent from many production vehicles, especially older ones, and can only be retrofitted.

This subject exhaustively and practically studies such retrofitting.

How are the existing turn signals connected?
How should the operating instructions' wiring diagram be read?
And how should it be copied in the vehicle?
Where does the aftermarket device connect?
The module does not work – why?

To establish practical relevance, work is done with the original operating manual and the original set of cables.
