Omega B – FL – combo – wiper switch with interval, cabling?!

Hey dear community, I have an Opel Omega B, BJ 2002, with Design Edition and strange white I have such a simple disc wiper switch without interval. Well, that’s why I got one with interval and a corresponding relay. The alternative to the interval switch with the VW relay doesn’t interest me. Today I tried to install the switch now, here I had the problem that the relay what I currently have for the windscreen wiper has no contact with the relay and also not in the slot I. However, according to the circuit diagram between the cable what comes from the switch with contact J comes to the relay I of the interval potentiometer. Now comes the thick problem I have at the contact J from the wiper switch the 2 cables actually go from or away from the poti (if you go according to the color), but then I have to connect these cables with the poti then I have no cable from the contact J to the relay I already have no connection. And I don’t know absolutely where the 2 Kable go I just don’t know any more, because I have an idea or I can’t find the relay without an interval.
