DO NOT DO IT. Im pretty sure a 5 year old kid could have done a better job. The wire job was a joke a best, and half of my dash lights didnt work. When i took the car back, they acted cool about it and kept the car to "fix" it. Got a call an hour later saying to come get it. When i did, they claimed it wasnt there problem bc while looking online at a supposed gm forum, they noticed that those lights tend to just randomly go out, but if i wanted to go buy the bulbs, we could "work something out" to get them installed
