To install the wiring adapter, you simply remove the mud guard from behind the driver side rear wheel. This is pretty easy to do, as it's only held on by a plastic push pin thing (you only need to give it a good pull). Then you will be able to see the brake light. Unplug your brake light wire, and plug in the T of the Hoppy.

First is a shot of the mud guard that you have to remove.

The second photo shows the brake connection that you mush unclip, and insert the Hoppy into. Just unwrap the protective tape, and pop the connection apart.
