Wireless charger

So I have a 2014 Harley Davidson Street Glide and I'm adding the wireless charger to my bike. I did an add a fuse, originally did it on the 20A radio fuse. Noticed quickly that the charger was still getting power with the bike off. Started to check all the fuses and noticed all of them getting power with the bike off (I've never had battery issues) has anyone else ran into this? If so, what fuse did you tap into? Any information would be great!
