Power block for gauges and etc?

So I was thinking about this the other day. You know how when you get a new set of gauges and you need to go looking for where to splice in for swith 12v or for the lights or for a ground? I was wondering if it would be possible to make like a mini power box with the ability to plug female connectors right into the box when you need one of the 3. So at the bottom of the box would be a ground wire, a 12v and a wire for the lights this way theres no more hassel, its just plug and play.. Tell me what you guys think...this could also be mounted on the dash or firewall that way theres no more splicing into the fuse box.
