Hello, I'm a first time builder and had a quick question regarding an illuminated AV switch and the NB v4. I want to have the switch led come on when I remove the kill plug from the recharge port, so after some research I came up with this for the wiring:

Switch Led+ goes to the NB 3.3v pad
Switch Led- goes to the battery-

Is this correct for what I want to accomplish, or would something else have to be done. Any help or pointers are very much appreciated.
