WUR, AAR (no power at plugs)

I have searched but cannot seem to find the answer.

I am trying to find out when the WUR and AAR should have power. Should they be hot all the time as long as the ignition is in the "run" position, or should the fuel pumps be running before these have power?

Also, the little green plug behind the CIS unit that tells my fuel pumps to turn on has only 10.4 volts when the ignition is on.

1) Are these things normal?
2) Where does the WUR and AAR get their power from (besides the battery and the wiring harness) meaning is there a fuse associated with them or what pin on the engine harness plug would control them?
3) What should the proper voltage be to the green plug (sorry, don't know the correct name) behind the CIS as stated above?

Thanks for your help in advance,
