First time poster!
I have a 2017 Giant Defy Advanced Pro 0 with the Shimano Ultegra Di2 groupset. I purchased a climbing shifter, SW-R600. It's supposed to plug into the right shifter, which is (according to the schematics online) should have 3 ports. However, when I pull back the hood, I only see one port which is already occupied by the connection to the Di2 junction box.
What gives? Is it that the groupset that comes with the bike is different from a generic version of the set, or is it that I am just a noob that's looking in the wrong place. I was fully prepared to install the shifter and re-wrap by bars... and now I am stuck.
Help! Any advice would be appreciated.
