The new box will likely have 4 wires instead of 3. The 4th wire will monitor the state of the washer pump and disable the delay when the pump is active. I will build a couple of the new ones so they can be proven out before more are built. When I am totally sure that they work I will swap out a new box for anyone with the old one.

I'll be a bit more precise with the wiring instructions this time. Some of you got...well...creative.
