Hey, we're all still learning, right? (I know I am.) Welcome to the
wonderful world of Audi electrics!

Yep, brown is always ground on these Audi beasts. Follow that wire
to it's end. It should be a common ground point on the body where
it will meet other brown wires. Make sure this point is clean and tight.

Probably doesn't matter. If there are no wire connections that require
it to be clipped on, then you're O.K.

I don't have my 7678 with me, but the manual will explain how to test
a wire. Now that I think about it, my manual was incorrect. I believe it
said to use the resistance (ohm) setting for continuity tests, but mine
has the symbol printed on the lowest voltage setting (200 mV?). The
symbol should look something like this: o))) where the "o" is a solid
dot and the parentheses get larger as they go out. I'm working from
memory here, so all of the above is very likely wrong. You'll know
you've got the right setting when the unit beeps when you touch the two
leads together. Once you've got the right setting, just touch one lead on
one end of the wire and the other lead to the opposite end. If you hear a
beep, the wire's good.
