no pics, but the housing runs under the leather all the way to the center (stem). This is cleanest, and works great.

I used to have them come out at the bottom of the bends (like you often see) but they just got caught up on things all the time. I think this was done back in the day because the old suntour barcons really didnt work all that well. with modern barend shifters (shimano or the diacompe/silver brands) you can run the housing fully under the tape.
