Could somebody that has a KHS AM series bike, please either take a picture of the cable routing over the top tube, or give me a basic description as to where the go?

I'm guessing the rear brake line runs down the middle, right? I'm using cable actuated discs, so do I use a small zip tie to hold the cable in?

I'm real close to having all the parts I need to put it together, and looked at the top-tube, and figured I better ask some questions, before I screwed it up.
