This involved completely replacing the existing wiring and getting a controller. And I had to run new wires. But it well worth it. No more going into the bathroom only to discover I failed to turn on the water pump.

Uses same switch location (which is now a momentary on switch instead of an on/off switch) and the same light on the monitor panel.

I want to thank klenger for some wiring diagrams he had posted a long time ago. He had made the same mod a long time ago and posted them in his diagrams. I duplicated his mod.
