After checking schematics on the site, I wanted to add auto lock/unlock to my 2000 Ford Pig, er.. Excursion. I wanted to modify the provided diagrams so that the locks reset each time a door was opened.
A few spare components and a six pack later I got this:
The doors only lock when the doors are closed the first time the brake is pressed after starting the vehicle or opening a door. By not using a resistor with the capacitor the charge is stored and the doors auto unlock when any door is opened or when the ignition is turned off.
Works like a charm. Timmy!
