I have one in my TJ and it works awsome. I had a chance to pick up some from work, so I am gettign 10 of them tommorow.
They are easy to put in and I can help you with it if you need help, but they make it super easy to hook up your accessories the RIGHT way.
I ran my lights, CB, crawl cam, ARB's, Winch turn on, everything off it.
They are waterproof and have 7 circuts.
In all honesty, you could use it as a fuse block for a custom vehicle, except for your couple bigger gauge wires.
Im selling them for $20ea
