This is the infamous auto-up window circuit from GBMINI (Ian Cull).
Plugs into the back of your window switches and gives auto-up windows by double clicking the window switch. This particular circuit was custom wired for a 9volt garage door opener and a second garage door opener. Since both door openers are operated off your door unlock switch, they have to be not on the same property. I used it for my house garage and my office gate. If you have a more modern opener that doesn't use a 9 battery, just chop off the 9 volt connector and solder the wires directly to the openers battery connections just like the other one i have on this circuit.

Perfect working condition. $50 shipped. Instructions included. Paypal accepted.
