Connecting the Garage Door Control Wire

How to Connect the Garage Door Opener Switch Step-By-Step

Konnected's Smart Garage Door Opener can open and close the garage by simulating the pressing of the wall control button. Using the included 3 meter (10ft) wire, this article explains how to connect the DOOR terminals on the Konnected device to the wire inputs for the wall button on the garage door opener motor.

Always unplug the garage door opener before touching connections or reaching the garage door motor with a ladder.

Identifying the Door Control Wire Terminals

The easiest way, if the wires are visible, is to visually trace the wires from your wall-mounted garage door button to the motor unit near the ceiling. Identify the wire terminals that the wall button is currently connected to.


These terminals are labeled and 2 on many older garage door openers.

On most Chamberlain, Craftsman, and Liftmaster garage door openers, these are the left-most red and white terminals. 

On some garage door openers, they're labeled BWC (for button wall console).

Connect the Wires to the Garage Door Motor Unit

  1. Unplug the garage door opener first!
  2. Most garage door openers have push-type terminals for the wire connections. Use a small flat-head screwdriver to press on the slot above or below the wire terminal to release it. On openers with screw terminals, use a screwdriver to loosen the screw.
  3. Without removing the existing opener button wires, insert the stripped ends of the included hookup wire into the terminals. You can drag and twist the ends of the hookup wires with the existing wall button wires to ensure secure contact.

  4. Replace the wires into the terminal, and push them tight or tighten the screw. Gently tug on the wires to ensure secure contact.

Connect the Wires to the Konnected Device

Asset 9-1

  1. With the Konnected device temporarily or permanently mounted on the ceiling, run the hookup wire up to the ceiling using the garage door mounting bracket to secure it.
  2. Insert the stripped ends of the wire into the DOOR terminals on the Konnected device, and tighten with a small flat-head screwdriver.

Hide and Secure the Wires

Make sure that the wires are secure and won't get caught by the moving garage door.

Tips to secure the garage door wires:

  • Use the mounting brackets for the garage door opener attached to the ceiling to guide the wires down to the motor unit. Consider securing them with zip ties (not included).
  • Use cable trunkings like the IKEA Montera or these products from Amazon to hide the wire and attach them to the ceiling.
  • Avoid using staples to secure wires to prevent accidentally slicing the wire.
  • Don't forget about the power adapter wire in your cable management plans!
