AFPR vacuum hoses and an electrical problem

[Gunnar]

After the rebuild there were some issues so i started going down the list of vacuum hoses. Along the way i found something sparking under the fusebox.
Turns out the previous owner had connected some thick wires with a bolt and shoved them out of the way under the fusebox. Anyone have an idea where they are supposed to go ?



Then secondly i have some issues with the vacuum hoses for the fpr.
When i look at the schematic i see the VSV having just two hoses connected.
However my vsv has 3 hose tubes sticking out.
At the bottom of the vsv there is one in location B that goes downwards, should i hook that up to something?
Then the A line should go to location C tube, then D tube connects to E line.
I can't figure out where the E line ends after going in the metal tube.
