My Model Garage opener is:
LiftMaster 3280M
It was just installed by the garage installers literally 4-5 days ago.
I dont want to start hacking up their work, and ruining the system, so I thought I ask first (lol)

From my understanding, the wired door opener acts simply as a switch, shorting the two wires will open/close the garage
The wired keypad seems more advance than a simple NO switch/button though.
Reading an older thread on this site, (lost the link), its believed that the wired remote control is activated by diodes, can anyone confirm this theory?
Question is: Is it safe for me to tap into the wired garage door opener's two wires? If its simply a switched N/O pair of wires, there must some voltage powering the night light on the opener. Thoughts?

- There is a green night light on the door opener
- Unit has a lock mode, and a button for the light

- I have a 4/22 wire near the opener, which two wires are in use for a door magnet, and two wires are free, homerunned to the elk panel
