I'm guessing this is too late to mention for you MTNWarrior since you already sliced open the plastic coverings, but for anyone one is following with the same questions, this might be usefull.
If you followed the wires into the head light bucket, you would have been able to get you turn signal power from there without doing an ugly hack job and the tedeous job of recovering it up to you stock wiring. The main soucre wire that leads up the left handle bar to the signal selector is an Orange wire and then it comes back down into the headlight bucket as Green for left and Grey for the right. From the haed light bucket it will be rediracted to the right handle bar for the right turn and to the rear for both left a and right turn signals. I learnt this from disecting the wires to re-route them through the handle bars.
Also for covering new wires, I've installed Stainless Braid brake lines, throttle cables, and clutch cable so I wanted the wiring to look the same and found the cheapest way was to buy fuel or vaccum lines that are braided for show cars and remove the rubber hose from the inside. The down side to raaw stainless braid line is that it'll act as a file when it vibrates or moves along the painted frame, for this I covered it with a clear shrink tubing I picked up from a locale electical supply store, a hobby shop or radio shack may even carry it. The end result is a clean smooth and somewhat shiny finish.
