Accessory Fuse box..??

[UVaJester]

I was wondering if anyone has added an accessory fuse box to there cars. I have too many wires running everywhere for gauges, boost controller, lights, etc... I want to to wire up a new smaller fuse box for just these things. I wanted to see if anyone else has done something similar, and it would be pretty straight forward, but I need it to be an accessory power line so these things cut off when the car is shut off. Anyones's suggestion would help.

If anyone was wondering... I found one at a marine/boat store... they are a little pricey ($25), but its worth it to me to make sure everything is done right... I'll post the results once I try wiring some relays and things to get this thing working..
