Slim,
The gold connectors are quite easy to fit and seem to be holding up well to use.
I have the dynohub wiring connection plugs facing the same way, AC current, so either to either works.
The rear light wiring connection plugs face opposite ways, DC current, so that the correct polarity is maintained as they can only be connected one way round.
Having the dynamo and rear light connections different means that I can connect the plugs in the dark and get them right every time.
I originally had both the dynamo and rear light plugs facing opposite ways (as in the old instructions) and it was easy to cross connect wires by mistake.
Some photos below showing my set up, I have pulled the plugs slightly out in one photo.
I am using the old handlebar mount on an accessory bar which works well for me.
