So I bought the H7/H9 dual kit... basically the process is to install the new bulbs, plug the power that would have otherwise gone directly to the bulb into a new harness. This harness routes the power to the ballast and then back to the new HID bulb. Naturally, all of the power cables, harness and ballast cannot fit within the weather-sealed headlight dustcap. My Dad and I went to work and we drilled a 1" hole into the lower outer corner of each dustcap. That way the cable would run away from the headlight assembly and congested front of the bike and down behind the fairings where I will have more space to mount the ballasts.
The quality of the kit was exceptional and I am very happy with the price.
The kit also includes a weather proof grommet that slots into the hole that you are required to drill into the dustcap. The entire package feels OEM quality.
