Hi Chuck. Welcome and congrats your puchase!
Here are a couple of pics from my bike setup which was set up by the installers in my house. The cable is attached to the handlebars, then routed down between the top of the bottle holders then back up inside the bike above the wheel and inside the frame of the bike from there so it's no longer visible. If that's what yours looks like it's correct. If it's fully outside the bike it's not right.
