The Amp Research installation is simple as can be. The wiring harness is cut to proper length, the color coding is the same as factory, and it installs easy (at least on our trucks). The safety is amazing, too. If they bump something on the way down, they will stop and stay until the doors are closed. Same with going up, if they feel resistance they will stay out. Plus, the step lights are really bright.
My buddy at work has them on his Dodge 2500 and I love them, but his install was a pain. He had to tap wiring behind his instrument panel, so he said it was a slight task.
My truck is basically completed aside from finishing my headlights, installing the running boards and buying/installing my mids/highs amp.
