Front flasher wire color?

[philbtv]

Installing dual color LED set. White running light/amber blinker combo for lower front arms. I need to tap into the left and right blinker lines. Is the wire to the front flashers the gray wire-(located under the dash beneath the handlebars on each side-see photo-which is upside down.) This color matches the color of the gray wire at the turn signal light. The good old shop manual has no color coding. 2008 GS Thanks!
