I read that the polarity of the wires does not matter when attaching to the Garadget, but is it important when connecting to the Garage Opener itself? (I have a Genie Pro Screw Drive / Model CM8600 IC/A - 1/2 Horsepower).

Thanks in advance!

On Garadget’s end there’s just a relay that closes the contacts so there is no difference which of two wires goes in what terminal. It’s important to return the wall button wires in their old positions in the opener because wall button has additional circuitry that is sensitive to polarity.
