see, I don't have a manual; know that I can look at one online and have. But there is another 12wire harness that it shows and I don't have it. Wasn't quite sure if I really need that harness. It does have the blue/green connection which I think is normally used for doors. I would think that the system has to be grounded but I can't figure out which wire if any to ground. thanks!
