I received a Opengarage device with additional security +2.0 adaptor.
The adaptor is a Liftmaster wall switch with 2 short wires soldered to the board.
The included diagram provide the instructions that
1.” the short wires should go to the OpenGarage”
2. “Long wires go to the door button holes on your garage system”
I interpret
1. the short wires FROM the liftmaster wall switch should go to the Opengarage device.
2: One end of the long wires should go to Liftmaster garage opener module installed overhead in my garage.
BUT WHERE SHOULD THE OTHER END of the long wire be ATTACHED onto this adaptor ? ( the supplied Liftmaster wall switch I paid $20 for).
The youtube videos on installation did not cover this either.
