I have a Thermador Range Hood model: VCK-1, and my fan switch stopped working as it no longer turns on/off.

I've located the part I need Bosch 414471, Fan Speed Control Switch. The new part I ordered came with 3 wires (2 red and 1 green) and my original part I'm trying to replace only had 2 wires (1 White, 1 Black).

My issue is how do I hook up the switch with 3 wires without adversely affecting my appliance. I did take pictures before I disconnected the original part so I know how it hooks up with previous wiring. But now I have two wires that are the same not sure which connects where.

Am I missing something, Please help me figure out what I should be doing. Thanks and any help is much appreciated.
