Brad;
I installed a 10 point fuse box under my dash near the steering column but up high enough so one can't see it. I took the switched hot from the ignition switch and ran it to one side of the fuse block and then jumpered the hot to the accessories that I didn't want to draw voltage until the ignition switch was turned on. The other items that I wanted to be able to turn on without the switch being on were fed with 12v hot all the time. Pretty easy to do. Good luck.
