I use the OEM switched lead to monitor voltage (I know, it probably reads low). Anyway, I didn't wire the grips through this because my understanding is that the load on this circuit is already pretty high, and I didn't want to make it even higher, so I ran it back to the fuse box. I think either works. BTW, for me to get access I had to remove the left side cover and swing the radiator forward. I could see it without moving the radiator, but my fat fingers wouldn't go in there to connect my lead until I gave myself a bit more room.
