BB is correct, but may I add a caution.
The black connector to the radio, contains two dark green/white wires, so make sure to look carefully at the photo supplied by BB and connect to the correct wire on terminal E. The other wire is the class 2 serial buss wire.

The photo you displayed, is of the underhood junction (fuse) block and the connectors circled are primarily ignition supply voltages, ground or crank voltage.
