Owner ignition fuse box connections?

[Fireman40]

I have a few after marke electronics that I have installed in my truck. I have them hooked up to the fuse panel under the dash but they are hot all the time. I don't drive my truck as much anymore and everytime I go to use it the batterys are dead cuz i left the dam accessories on. It there a way that I can power these electronics so that they will not have have when the key is not in the ignition. I know I could splice into and ignition wire but I would rather not if I dont have too.
