I got the relay kit for my samurai about 4 or 5 months again and it did work great. Untill it desided to go out on me. The company that I bought it from said that they hadn't heard of it going out yet so thats why im posting this. If your sammy don't start outa the blue and you hear a very quiet clicking sound from under the hood most likely it is that box. I spent 3 days chasing wires and finally figured it out. So start there if it happens to you.
