expensive but functional
It is an expensive item for its size but essential to install Di2

Internal wiring junction box - picture is wrong
If you are going to run your Di2 cables inside the frame tues, this is the part you want. The picture is of the external mount box, but the internal box is the one I received. Just remove your crank, plug in your 4 wires, tuck this back into the frame tube, reinstall the protector sleeve and crank and you are all set. A very clean install of shifting perfection!!

Works fine
I decided to build my new road bike with Di2 electronics. I didn't want to drop $1,500 at one time on the kit so I bought one component at a time. It all came together nicely and all components work fine. I highly recommend this product.
