Where the electrical wires enter is a pnel that comes off with a couple screws. Remove this panel. Then you will see 2 small plastic wire nuts, this is where you will attach the wires back to. One wire to each wire nut. There should already be a wire in each nut that goes on into the ac unit. You will remove the wire nut and twist them back together.

Hi,

The panel on the side has screws in it. Remove them and remove the panel. Then to get to the control panel, you have to remove the innet sheet metal panel.
Best regards, W/D
