Key on power source

I have a 1995 Ford F-150 4.9. And, I would like to run a secondary fuse block but I would like it to be wired to only turn on when I have the key on or in the auxiliary spot. Does anyone know where i can find a wire like this. The fuse block will power lights, airhorns, subs, and gauges.

Thank you for your time!!!

With that many added loads, the fuse box must be powered directly from the battery. If you would like the fuse box to turn on and off with the key, then you need to add a relay between the battery and the new fuse box. The relay can be powered by any key-on source in the factory fuse box, since it draws very little current. You could buy a fuse tap and tap a very small wire into the radio fuse, and run this small wire out to the relay under the hood. That would turn the relay on which in turn would power the new fuse box.
