Good question... I have a couple leads under the nose fairing that I connect a few accessories to. This way I'm only splicing into the bike's wiring harness once. It's been a couple years since I spliced into the switched power, so I'll have to check the diagram to say for sure what it's to/from. I do remember the splice was made on a wire that runs past the thermostat.... I know that doesn't tell you much. The neg/ground is EITHER from the headlight, OR can be traced back to the grounding bolt in the frame that the starter is connected to. Wish it was in front of me at the moment, but I hope this gives some clues. Sorry so vague.
