This is a Shimano Ultegra Di2 Front Wire Harness. This connects your front controls to a single wire to travel through the frame or externally to the junction box near the bottom bracket. This also gives you a power and programming button, as well as a battery level indicator. It is usually mounted just beneath the stem.
