The wire harness kit is well made and the install in my Jeep was a breeze. There rocker switch fit perfectly into the accessory slot panel. As others have mentioned, I did have to extend the length of the rocker switch wiring, but that was not a problem if you are even a little mechanically inclined. The actual instructions provided were clear and concise. I would recommend this harness and will buy one again when it is time to install my additional rear LED lights.
