I hooked up the same lights on mine and when I did I hooked them in with my running lights. Now, on my bike they were a light purple (i think, was a while ago) which I found from my schematic in my shop manual. I'd look for you, but manual is in storage in the trunk of the bike. If you don't habe a schematic, you can follow the wires from your fuse block where the lights go in. You should double check with a voltmeter first, but I would recomend against this, and suggest that you get the manual, but it is your ride...... Or, if your not using it yet, there is an unused line that runs back to your accesory switch on the dash panel. The plug is under the seat in the vicinity of the battery. Good luck....
