The latest and greatest fuseblock is available from

Each of the six (6) circuits can be individually set to always on or switched power by just moving the fuse.

Switched power uses a lower power switched lead to activate the included 30A relay, so you can run full power to those switched accessories.

Radio Shack Superlock Fastener should hold it securely in the tail.
I bought #6 machine screws with self-locking nuts to mount the bottom plate.

Sure is a nice looking piece, eh?

And here it is installed in the tail.
