seems like all questions are answered, as there is no reply for such a long time. This is the best documented thread I came across, thanks to all, who contributed.
Many questions answered, where I was already sitting and thinking for a long time. Today I wanted to ask, where to put in the switch title light, which I got recently...
This is also answered already, now I have to find that strange connector above the radio or in the strapped wires there. I have the headlight/key in buzzer, found the pink 3 pin connector for the glove box light (but only the middle pin is a connector) and thought I have all the wires, but maybe I'm missing the harness used for the maplight, the switch panel bulb AND the steering column title lamp, and the time delay relay too.
