Loose wire

Sorry  double post,I thought I posted  here anyhoo I seem to have a loose wire in the boot it's beside hydro roof relay and it's hooked up to lots earths

My fluid is below minimum where do I fill it from ? Can't see where there's an opening or some sort of cap. Can I use power  steering fluid?

Final question of the evening. There's two lilac wires either side of the back seat what are they for? Any ideas ? Thanks folks I'm going flat out on this car for the weekend a few bit's welding to do tomorrow and Sunday 

That  fupper there and two more bits around windscreen. I have a cut piece from a scrapped cabby , kindly donated by James mk1 eighty

The purple wires are connected to the press studs both sides of the rear seat and disable the roof from closing when the hood cover is in place with the press studs connected.

You have to check the level with the roof open. You fill it through the bolt hole just above reservoir (bellow the yellow sticker). There is a specific hydraulic fluid, see https://vwgolfmk1.org.uk/forum/index.php?page=topicview&id=helllllpppp%2Felectric-hood-hydraulic

Thanks mate , would never have guessed that  👍🏻
