In an effort to clean up the wiring in my X, I took a ride over to the local Radioshack looking for a fuse block (I saw someone had one, but I did a search and didn't come up with anything). As usual with Radioshack, I came out without what I'd been looking for. If anyone knows where I might purchase such a device, that would be great. If not, this weekend's project will be to make my own. Thanks.

go to an automotive parts store. they should have plenty of stuff to build your own fuse block

You will find all sorts at a marine supply store.

Good luck....
