Positive to Negative / Vanagon door lock

So I upped the Capacitor to 2400uF and doubled the resistors to increase my energized time. It seems to stay on just a skosch longer now. I have only bench tested it so far. But it seems to work fine everytime. I have it in a sealed Project Box. Before I built this and what caused me to build this was a constant on relay which was switching + to -. But when I hit the door lock with the vehicle running sometimes it would send the window up. As I think about it now, the unit should be blocked out when the ignition is on.    In my project box I wired a N/C relay to prevent this from happening, but I think I have over thought this.     I will install it and see what it does.
