Well after taking my old HU out and installing the new one, I can say this much, I am never going to big business installers to get something done ever again. I don't know if it was lack of research skills, common sense or just the ability to take a little pride in your work, but it is pretty clear to me now that I am going to have to do everything myself. Which is kinda great, I love to learn new things.
I would like to take the time to thank everyone on this forum for sharing, even just a little bit, because it is good to know there are others out there who take pride in what they have. I don't have much in life, and I don't ask for much and it has served me well. I love my Z and its nice to be around others who love theirs just as much
