5. Connect to Opener Release Mechanism: Locate the manual release lever on your garage door opener's trolley. This lever typically disengages the door from the opener's drive mechanism. Connect the end of the emergency release cable, possibly using the triangular cable adapter, to this lever. Ensure the connection allows for a full pull on the cable to disengage the opener.
