Wiring Fault...

Sidelights are permanently on. Everything else works perfectly but the first stage of the 3 position headlamp switch does nothing.
If I disconnect the Green/White wire from the fuse box (I'm assuming this is for indicators as I have no Haynes manual with me) the sidelights go out and the 3 position headlight switch works perfectly fine, however, with all lights off I have no indicators and no windscreen wipers. As soon as I put my sidelights in (via the switch) I get indicators and windscreen wipers.
I'm assuming the indicators and windscreen wipers share the same 12v feed.
Any help would be greatly appreciated! And if someone could try and upload a picture for a wiring diagram for a 1991 mini city 998 that would also help.
I'm an avionics engineer by trade so no need to dumb down on terminology 😊

When you have circuits being powered by something like yours where the sidelights are powering the indicators and wipers, I usually check the back of the fusebox to ensure its not corrosion linking the rear contact riveted connections, if its not that then its a case of out with meter and tracing the circuits, have a quick look at the terminals behind the grill those bullets are famous for effecting what works or finds another path to earth if dirty, but I can't see the wipers being effected by those.
If all the above looks ok then I would pull the connections off the circuits and check the feeds and earths with the wiring diagram, and back track to the connectors inside the car. Not unusual to find now that the amateur electricians have cut into other circuits when power is lost on the original feed, I just did a MGB where the whole interior was wired in Blue thin wall wiring, including the earths !

It me just small things that lead me to think it's not been connected properly though. For instance when I bought the car, the water temp wasn't connected and the wire had been snipped and tied away. Also the oil pressure switch wasn't connected and wire had been connected to the + side of the ignition coil?
I'm all for trying to better yourself by learning how to do things but why do some people just live with the 'that will do for now' attitude haha
