That's how it is on my sportbike, hidden in the horn....I guess the 2.5 pound bottle strapped inside the swingarm may be a bit of a giveaway.
When I ran it on my old Mustang, I had the system on switch tapped into the stock foglight switch I got from the JY and activation by throttle switch. Completely stealth.
