Kit is designed to include everything needed for installation. Based on the wiring experience I would say that yes it has everything to make it work but it doesn't connect properly like I would like. Also, the horns sound higher than a train horn, but still very loud, but no worse than what you get for $300. I would recommend this kit as a good starting point or way to get on the air. If you want a real train horn tone, you have to buy a real train horn, and that doesn't come cheap.
