Cable length is unknown yet.
Advice is warmly welcomed...
- Junction A: SM-EW90B (5 Port)

The Junction A is required for charging, trim adjustment, programming. As for ports you can make the levers a J-Box too. The DA have 3 ports per lever. So the Junction B isn't always needed.
Also note the Y cable could eliminate Junction Box B
EW-JC130
The handle bar end J box should also be out soon.
This made the front really clean. Any wire can go to any wire.
