Ok, I had some question when I wired mine up also. I got through it without burning the house down and it still is working like a champ. It is not as bad as you might think.
I start out buy cutting a 3 inch section from a extension cord. I use the three inch piece to get a couple of jumpers. You should use a three inch black and a 3 inch white jumper to do this job properly. O----------------- |------- |----------------E extract the center piece and you will wire the switch with the other two sides. That center piece is not junk it is your jumpers.Peal the ends and away you go.
1st. Your ground - wire it together.(The Ranco is not grounded) If you don't have a ground (green or just straight copper) just bypass this step. I used an orange extension cord 3 prong so it does use ground. I think it is best to as it can support the load of a freezer
2nd your hot lead. The white wire. You will need a 3 inch jumper (white) to do this piece. Connect the white lead (wire from the right side- the a/c "IN")and the jumper to the 120 connection and the other end of the jumper to the "C" screw. Then attach the "Out" hot lead (white wire from the left side - the a/c "OUT") to the BO screw. This is the switch connection. Hot lead here is the one set up for the switch to open and close. aka on/ off
3rd your common connection (Black wire).You will need a 3 inch jumper (Black) to do this piece. Connect your "Out" wire(Left) and "In" wire (Right) together with a small 3 inch jumper. So, Tie all three together with a wire nut. Then screw the other end of the jumper wire into the "COM" screw.
solder and tape all the connections as you deem necessary. Screw it down and plug it in.
