The wall control button, a Chamberlain MyQ unit, offers advanced features like programming the door to stay open for a specific time or a motion sensor to activate the light. First, strip the ends of the wires that will connect to the button. The terminals on the back of the button are labeled red and white; attach the corresponding wires. To mount the button, start by screwing in the bottom screw into the wall, leaving it loose enough so the button can slide down and hook onto it. Once the button is hooked, secure it with the top screw. Ensure the wires are neatly routed. Then, run the wires from the wall control button up to the main garage door opener unit. The opener has four color-coded terminals at the bottom for connections: the red wire from the button goes into the leftmost terminal, and the first white wire goes into the adjacent terminal (press down on the small button or tab next to the terminal with a screwdriver or thumbnail to insert the wire).
