I have a switch box from a police car that I want to install for various things in the future. I'm not sure where the best place to pull power from would be. I have it down to either the positive side of the battery (driver's side) or the power lead that feeds the fuse box under the hood. Which would be better? I know either one of those places would not be keyed power so I would have to be sure all accessories are off when I shut her down. 

 The switch box I have is rated for quite a bit. Switch 1 is routed through a 40a automotive breaker, switches 2-6 are protected by 20a blade type fuses in the rear of the box.

 Any help or ideas are appreciated. Thanks.

 I've done something similar. I've made a list of things I need from a store and forgot to take the list with me
