William,
That's not my bike, just a web photo for demonstration purposes and I misremembered the name as Expedition when it is actually Excursion. In fact, it appears that this one has had its lights, generator and controls removed. Here's a link to a thread with pix from [MENTION=24271]wahoonc[/MENTION] of his bike that is complete, although sporting a bar change. You actually posted in that thread.

Giant Excursion 23" frame for 6' rider?

Pic of his bike, but what you really need is non-drive side photos, a novel request, to see how things connect. Perhaps he'll chime in and provide some more detailed photos of the light setup.
