The kit came very nicely packaged with the most laid out program of anything I have ever installed. It was a simple install...all plug and play with those German plugs, can't recall their name, and even the grease to put in them. It also came with a plastic covered, spiral bound manual for installing, operating and warranty info. I can't tell any difference between the performance of my Bennett's I had on my flats boat. Can't say enough good things about them,,way cool. :!:
