1970 base cougar wiper/washer switch wiring

Putting AAW wiring harness in.

I am working on the wiper/washer wiring now.

I have the original harness from the motor to the switch but have three wires at switch that I need description of and what they hook to

  1. White with black stripe

  2. Orange with white stripe

  3. Green

I believe the orange/white is switched power
The green is feed to washer pump

The white/black I don’t know can you verify or help with this??

Thanks
