Yeah I have one for my twalcom spots. You want to tap into the blue and white turn signal cancel wire. I tried cutting into the loom under the left side panel but couldn't find it so I wired it into it on the bars.
Use them or don't use them... Mine have been fine, no problems whatsoever. You can solder joints if you want, it probably would be better, I chose not to.
So the trigger wire from the indicator cancel switch is blue and white, and if I take a switched power supply off the canbus wire on top of the tank I'm done bar the relay and the rest of it but thats common for any relay. We will cut into the loom and solder it in, just concerned you couldn't find the wire without cutting open the sheath on the bars
When we done our 1200 we managed to hide everything http://www.adventurebikerider.com/f...ights-to-a-r1200gs-using-an-autoswitch-7.html
If I'd taken a bit more time I probably could have hidden it all away a bit better. I'm a total novice and I barely figured it out. But it all works fine with no problems.
