Auto Lock New Prius at startup

Have a new 2006 Prius and what it to automatically lock the doors when I push the power button.  The requirements require the brake to be engaged, then push the Power button.  To turn off the car you push the park button, depress the brake, and push the power button to turn off the Hybrid system.

The Connection pointsare .....

IF1-5 Connector = 12V from the brake switch.

IE3-6 Connector = ground output to the negative lock line.

The line from pin 5  of Power Switch to pin 14 of the Power ECU is ground.

IE3-5 connector = 12V after startup and delayed off 43 seconds after car is turned off to close windows.

Will the relay setup uploaded work and do I need some diodes for isolation anywhere.

Here is the relay layout as the first upload, I guess was to big.  Any help would be appreciated before I attempt the installation.  My question is do I need diodes to isolate the ECU's and the relay on the right as to if I need some kind of delay before this relay works.
