pump wiring

[kirilltest]

Hi All, Maybe someone can help me with an idiotic question.

I have low/high-speed timers total 4 wires out to pump (two loads, neutral, ground), the new pump just arrived, and I am confused about how to connect. Pump has a toggle switch, however, I already have high/low timers in an electrical box. My pump is 115V prewired.

What position need to be a toggle switch?
What wire need go to 1, 2, 3 connection?
