Accessories on until door open

Hello,

I am hooking up my radio to stay on after the ignition is cut off until a door is opened.  I used this diagram.

The problem is that whenever i turn the ignition off and open the door the radio is still on and doesn't shut off unless i unplug the relays.  Am i using the wrong size diodes?  They are 1N4001. 

hey...i found it and installed.  it works great. 

thanks
