    I recently installed an older liftmaster 1050-6 garage door opener in my garage.  The back has red black white and yellow connections.   I know the opener goes to the red and white connector, but I have tried several combinations and I can't get the sensors to correctly wire up.  What would the black and yellow connectors go to if not for the sensor.  Thanks!
