Finally, the inside of the remote, showing the two soldered wires. If you can't read a board (I can't..), just experiment with the lead wired to the switch and find out which two points make the opener work your door. I hit it on the first try. I don't think you can do any harm here. Once I found the two leads, I just added a touch of solder to hold the wires in place. Buttoned her all back up and I'm in business. Nothing more satisfying than hitting that button on the way in/out. (ie: lazy!)
