Can anybody running secondary inline levers post a pic of their handlebar setup?

I'm considering getting a Tektro inline lever for my new fixie beater, but I'm having a hard time figuring out the cable routing.

Here's the basic plan: upsidedown POS brake lever (Cherry brand, baby!) at the right bullhorn, cable routed along the bar and popping out to go to the inline lever near the stem. Just not sure of the specifics.

Alternately, I could get a new TT/pursuit - specific bar-end lever...
