This sounds odd. Are you trying to replace your HVAC thermostat? If so, this is probably what you need:

No idea what Dometic sent you, but it does not sound right. Replacing the ct thermostat takes just a couple minutes; pull the face plate off, two screws and a few wires. Take a picture of the old one before you remove the wires; put them on the new one the same way.

They just sent me new face plates, but it took almost 3 months to get them.
