I am an electrical novice and was worse off 3 years ago when I did the install. No issues with my cheap harness aside from those customer service related. It took me about 6 hours to do. Wire by numbers is great and if I need to go back troubleshooting is really easy.
Me: Hi I just purchased a harness and I think it is missing fender grommets
Phone Rep: We have been selling that harness for 20 years and no one has ever had a problem with that before
Me: I'm sorry did I miss something?
Phone Rep: If you really want that you need to buy the $24 dollar head light harness
Me: wow great customs sevice!
