Heater Demister FRUSTRATION!!!

I'm confused like everyone else. Maybe a pic of the dash you want to put it in would help. Good luck

Sorry for the confusion

The first 2 pics are the heater demister panels I bought. These 2 panels are both incorrect and dont fit my 73 Duster.

The 3rd pic is the blower motor switch that was plugged into my harness when I bought my car. That is all it cam with. There was no heater demister control panel. I am looking for the heater demister panel that fits with this switch.

Hope this is clearer
