OK,

I was going to go through this whole convoluted exercise in electrical wiring to try and save a few bucks, but then Marion at the Daphne, AL Home Depot steered me to this item in the clearance area...



Saving me $34 and allowing this....



About an hour of real labor and the project was done and installed in the tank's stand...



Looks like I'll be putting the kit from AHS on order a little earlier than expected.

More later,
Pat
