I would shy away from putting it in the enclosed headlight unless there is plenty of room in there or there is good airflow through the headlight. These load equalizers generate a lot of heat, especially if you get stuck at a long red light waiting to turn or forget your blinker after a turn. I have never seen one of these "home made" load equalizers (from my plans) melt or cause an issue, but I have seen more than one Kuryakyn-made load equalizer get so hot that it melted. In some cases when the Kuryakyn ones melt they also damage other wires that are too close creating a whole mess of other problems. The best recommendation would be to zip tie it to the frame or some other piece of metal that can help act as a heat sink and/or someplace that gets airflow as you move - but normally just placing it somewhere that isn't enclosed and bundled up to prevent it from dissipating heat will work just fine. I do try to keep them separate from other wires just to play it safe, that way if something terrible did happen at least it won't damage the rest of the electrical.
Realistically you can put it almost anywhere and it should be fine, I just don't think an enclosed environment like the headlight is the best idea. They tend to be cramped quarters already, full of important electrical wires, and you compound the heat issue because of the headlight's warmth.
As a side note, have you considered one of these?http://tech.bareasschoppers.com/electri ... t-flasher/
I haven't confirmed fitment for many other makes/models, but most metric bikes and even a lot of Harley's can use this flasher module. I checked the Custom Dynamics website and it does show fitment for your bike.http://www.customdynamics.com/trick_fla ... OT_Flasher
It looks like it may be a hard wire installation rather than just plug and play, but this flasher eliminates the problem of heat from load equalizers, one flasher will work for both front/rear blinkers, and without load equalizers you are actually freeing up that power to be used for other accessories on your bike. Just something to consider.
