At first I thought it would be the hi/low headlight wires, which to me are "position" wires. I don't see it hooking to the turn signal wires as then it would only work when that side was active. Maybe they mean the running light wire for the small light located below the headlight bulb? Europe has those on the front, here we just have the park light wires on the front. If I had to guess, it would hook to the park light which could be tapped to on either side, and is always active when the bike is running.
