replacement harness is definatly worth it. I got my CDC sequentials from american muscle.com and they were about a 10 minute install. Getting into the actual harness aka taking apart your trunk area was the only thing that took long. Otherwise, pop the bulbs out of the old harness, into the new on. Plug it in, and you are good to go they even label them 1,2,3 for you :bigthumbsup
