I just installed AMP steps onto my truck on my own, it took me about 3 hours to do so, and it wasn't to hard, just a lot of little steps. The wiring wasn't hard at all, the instructions give you a pretty good idea where to run the harness. just make sure you follow the torque pattern that they give you, one of my steps had a little gap in the front and i had to go back and re torque everything to get it to line up.
