Garage door hack possible with window switch???

You will have to set the voltmeter to diode test. That's the function when you touch the two probs together and the voltmeter beeps.
Then you need to place one of the probs on the connects, and run the other prob thru the holes, one at a time.
If the voltmeter beeps, that means that the hole and the conntact are connected.
In this case, you can solder the wire to the hole instead of the contact itself.
And yes. Start with the 6 holes in the center, and you can also check the 3 on the left.
My guess is that you will find the common. Not sure if you will find the other side.
Just by looking at the board.

Solder wires to the two terminals below the red dots I've placed in this photo.
Run one wire to terminal 4 on the switch and the other to either terminal 1 or 2.

That's it. No need to mess with anything else.

Hello Gentlemen, I appreciate all the help so far. I had a little emergency today with my cable modem out, so no anything. Will try to follow recommendations tonight or tomorrow and update soon.

Ok, so this evening I had a chance to pull out he multi meter and check the board. Pics aren't great, but what I found is that the 4th hole, in the line of 6, when touched by one probe and then touching the top part of the contacts seems to be the common as the meter zero'd out each time on the top row of contacts and the middle row of contacts. So that means that ironically, #4 on the switch wire is soldered to the 4rh hole as the common and the other 2 wires each go to their respective contacts.

Well done.

Thank you sir. Will buy wire and hopefully solder everything this weekend. Thanks for the help.
