Trying to add a wall thermostat but am struggling to get it to work. I purchased the 8330-752 control module and the ac is an 48203c866. I was trying to use a house thermostat (running off batteries) but can’t get anything to happen. Don’t know if I need to try a different thermostat or if I have the wrong control module. There are 4 wires from control module. They are fan hi and low, compressor and 12volt negative. I ran the yellow compressor wire to yellow on the tstat. Then I ran the fan wire to a toggle with a single wire coming off going to the G on the tstat. My 120 is all hooked up and shore power is provided. Nothing happens no fan or compressor. I didn’t hook up the blue negative wire as I read somewhere online it wasn’t needed. Adding some pics for reference. I ran a tstat wire from ac to wall unit.
