Bob M,
YOU DA MAN...wish I had the tech. abilities reqd. to figure something this complex out in the first place. Seriuosly, your aside for the non elec. eng. prone was too deep for me.
However, if you get a handle on this thing & produce a few "plug & play" units (harness, controller, DETAILED instructions, etc.) You can count me in as your first customer.

Hope ya get it to work, Ldub
