COMPLICATED..yes. indeed. just got in late last night...will post up some pics for yaI more meant the learned stuff. I worded it wrong after i re read it. I don't know how much of that relates to how it runs on a daily basis if you constantly power off the PCM. Or what it does to teh keep alive circuit and other related stuff. Cars are too complicated now...lol
