Joe, just a thought in passing:
All those colere-coded plugs that you were so kind to post, do not exist on the Magic Pie III. That illustration referrs to the Magic Pie II, which I also have. Magic Pie version 3 has a single multi-prong male plug (with numebers on it, 1,2,3,4) that most of that stuff plugs onto. Makes for a much neater installation--that is if Golden Motor decides to lengthen the brake and throttle control wires that are too short to fit on most USA bike handle bars, and certainly not on the wide bars of a Beach Cruiser.
Just thought I'd mention it.
Thanks again for your help.
