As described by other posters the horn, taillight, and turn signals will run off the battery DC power and therefore when you turn the main power switch on they will turn on. The headlight will run on a completely different power circuit and will run off the stator AC power. Therefore the headlight will only run when the bike is running.
If you want to keep the stock Yamaha switch with the little red LED:
- Take the Tusk red wire and splice that into the stock Yamaha brown wire. This brown wire can be found by following the stock Yamaha main power switch to the four pin connector junction. The brown wire is coming out of that connector junction and goes into the bike.
- Take the Tusk black wire and splice that into the stock Yamaha black wire. This black wire can be found by following the stock Yamaha kill switch to the two pin connector junction. The black wire is coming out of that connector junction and goes into the bike.
So now the stock Yamaha main power switch will send DC battery power through the Tusk dual sport kit and power the horn, taillight, and turn signals.
See my above post on how to connect the Tusk headlight hi and low beam handlebar switch to the stock headlight. Once again the way described will run the headlight off the bike's stator AC power and therefore will only run when the bike is on.
I guess if you wanted to get really fancy you can have the best of both worlds and rig it so the headlight can run off the battery DC power when the bike is not running. The way to do this is by splicing in one end of a red wire(supplied by you, not part of the Tusk kit or from the stock Yamaha wire harness) to the blue Tusk headlight switch wire. Then splicing in the other end of the new red wire supplied by you to the stock Yamaha Red/Black wire coming from the stock Yamaha main power switch. I have not tried this but my theory is the low beam headlight will act just like the little red LED in the stock Yamaha main power switch. It will turn on when you switch the light on but turn off when the bike is on, this will then allow the headlight to switch over to the AC stator power. Now I am not sure if you also need to connect the black wires too but I am guessing the existing black connections will work. I will try this out and let you know if it works but this may take until the weekend. You all can try this at your own risk beforehand. Who knows it could blow up your bike or something! Well probably not but I don't want anyone blaming me for any sort of damage to their bike.
