How Do I Install These

The one piece of leftover things to do, with regard to the motorcycle and sidecar I just bought, was to go up to the dealership yesterday and pick up the windshield for the sidecar, which had to be ordered.

I’m fairly well mechanically inclined, and so it’s no big deal to install the windshield. I just have to do it. I will be out there doing it this morning.

In the state of Connecticut no tail light is required for the sidecar, but.........In the box with the windshield was to tail lights. I don’t know where they go. I don’t know how to install them. I can’t imagine ugly wires running externally from the back of the sidecar to the back taillight on the bike. Does anybody know how to install these? See attached video of the items.
