As simple as they come...
My biggest complaint with the system is that there's almost no documentation, just one tiny pamphlet that doesn't even completely match the product. Fortunately the system is so simple I was able to figure out how to install it with the help of various online videos installing similar BSD systems. I was working by myself so the install took a couple of days. The hardest part was figuring out how to connect the system to a switched 12v power supply. I opted for a "add-a-circuit" fuse tap that I got a local hardware store. Although the system is simple in design, there are lots of steps involved, including removing the back bumper cover. However, as long as you are patient and tackle each part of the install carefully, the end result will be worth. With limited testing so far, the system works exactly as I had hoped.
