How would I swap out my stem-mount junction box with one of these: http://www.madison.co.uk/products/cycling/transmission-braking-components/di2-accessories-spares/ew-rs910-e-tube-di2-frame-or-bar-plug-mount-junction-a-charging-point-2-port/
Is it supposed to be used with the shifter Y-cable? Is there another way to wire it? I presume I'll have to drill the bars unless I can get to an existing cable port?
Just wait till Pro alu Di2 bars are available
buy one now and try it out with 3 e-wires.
L to R L to RS910 RS910 to Junction B
if 3 wires doesnt work then you might need the Y-Cable
then just take the time to wire them internally on your current bars (presuming they have some form of internal wiring)
