Working well now

Since this part was not identical to the old one, it took a bit of analysis to install it correctly. (The old unit had 4 wires, the new one had 6. I have no idea what the red wire are for!) A few instructions and a schematic would have been useful. Also, it took some trial and error to determine that I needed to add a cut off switch to get things to operate correctly.
