I have two questions regarding a window AC unit. I am confused by the wiring diagram.

First, the line voltage seems to go initially to the Compressor thermal cut out, then to the C terminal. The Compressor R terminal connects to the Capacitor H, and the Compressor R connects to the Cap unmarked. (Cap F goes to Fan).
My confusion comes from the fact that the Cap seems to be "downstream from the current flow through the S(tart) windings. The unmarked Cap terminal seems to be a neutral junction (receiving a white fan wire in addtion to the Compressor R wire) and then running a third wire back to the control panel where it hooks up with neutral plug wire.
But for the Compressor to get a boost from the CAp at its S terminal, it seems the current flow is Compressor to Cap instead of vice versa.

Second, where are the neutral return wires for the Compressor?
