Correct. The wire going through the grommet powers the controller and the controller powers switched hot to the outlet. The freezer plugs into the outlet. The other wire in the pics is the power for the factory installed light and temp alarm(which has an on/off switch on this model freezer).
IrregularPulse, I didn't want to cut up the factory wiring or have a separate control box. This was the neat and organized solution.
