My other car is a MINI!!!!
dude, just pull it apart and look at it.
You won't see it being wrong or right, it'll look the same.
it's an arm, 50mm long, on an M8 spindle with a spline. it's just a few splines off. nothing to see, it'll look no different when you're done.
Turn your wipers on, let them park on their own when you turn them off, they'll go down, then back up a tad as you described.
The motor is then at it's end point. Undo the centre bolt and price the arm off the spline, push your wipers down to where YOU want them to park, then push the arm back over the spline and do up the bolt.
there really are no more questions to be asked about setting them up, just have a go!
