Not sure who would be interested in doing this or not but anyways here are a few pics of the garage door opener mod I did with a HD FLHX CVO electric bag lock (momentary) switch. A 12v 3 button Genie remote was used. Button 1 was soldered to switch and +/- is going to the cigarette lighter for a switched power source.
Not to hijack....but maybe someone else will remember. I know you did yours with a GENIE. I remember seeing one done in the same manner with a CHAMBERLAIN, which is what I have.
I did the exact same mod with an Overhead Door brand remote which was 12 volt. If you want to do this mod with a remote that isn't 12 volt, either skip hooking it up to bike power and use a battery, or use a Radio Shack voltage step-down (cheap) to get from the bike's 12 volts to whatever your remote needs.
