On my '10 it is the purple wire with the gray tracer on the headlight switch. You'll need a grounding point as well. I ran a wire behind the console to the factory grounding point behind the glove box.
I had it happen when I had the STRs on my car. Right front blew with less than 50 miles. The warranty process is kind of a PITA but, Koni came through with a new unit.
If you don't have any friends or feet but, do own a compressor, get this http://www.harborfreight.com/automotive-motorcycle/brakes/brake-fluid-bleeder-92924.html. You can bleed/flush the entire system in about 15 minutes. Works great!
You can tap into the purple wire with the grey tracer off the light switch; same point Roush uses. I couldn't find a convenient grounding point near the light switch so I ran a wire under the dash and behind the center console to the factory grounding point behind the glove box.
