in reading other posts about fuse blocks and such.... I think I got this right

1) the stock connection for the accessory lighter plug that goes in the cubby is switched (hot when ignition is on or set to accessory) correct?

2) there are two auxiliary connections on the stock fuse panel. One is switched, and the other is hot all the time. correct?

> general "I'm an analog kinda guy" electrical question.

3) can u split a usb into two connections to use it for charging only. I don't use the usb in the bag for music, but would like to charge various batteries phones ect.
