LHD W.G (West Germany) wires from dimmer & dash switch to headlight relays?

[Rascal21]

Hi all!

Making my usual annual nagging topic on how I can fix AE86 headlights here.
Been reading my arse off on the diagrams but I understand no more of these gibberish tell-tales today than I did 5 years ago when I got the car, but from my slightly more accumulated car mechanics knowledge at least I have pinpointed what I need to do (Make new relay setup and screw the OEM one, just leave it be).

Like title states I`m very interested in finding out which wires goes from dimmer and dashboard switch and to the headlight relays on the West German AE86`s and whether they provide ground for the relays or power as signal! Got a bunchload of relays and I`m very anxious to get the car on the road now
