Has anyone successfully used the USCartool A500 Crossmember?

Did you use relays in the system, or just the switches? I would also put an inline fuse in, if you didn't already. I like the clean looking set up though, looks cool and convenient.
No relays at this time, and I will be adding an in line fuse probably this weekend, just didn't have one when I hooked up the last wire this morning, which was the key on power to the tranny.
