I don't know way by I can't seem to figure this out. I'm trying to replace a standard 3 way switch to one with a high water alarm. I was trying to rig this set up on my forward pump that never sees water. My thinking is if this pump cycles on there is a problem. The existing wires are a red + a black- and a green and white from the pump. The pump has a separate float switch . I spent hours today trying every combination I could. I was able to make the alarm go off but not turn the pump on at the float switch. Any thoughts????

I did start by connecting the existing +red to the post on the back of the fuse

Interesting panel. Innovative use of 2 float switches. If the first float is part of the pump, that may be the cause. Each float gets connected to the panel independent of the pump, apart from the shared negative leads. I appoligize if I have said something you already knew.
